hi everybody,
Who's up for a challenge? I chose these numbers at random.
PUZZLE 1
3,5,7,2,100,and 50.

Use these numbers to make the number 953.

Rules:
Use only these numbers
No number can be used twice
You do not have to use all the numbers
You can use + - x or divide.
You can use brackets.

First one to respond with exact answer wins. If you post later but you have a substantially different answer, you win too.
If no-one gets the exact answer then closest answer after 12 hours wins. (competition closes in 12 hours)

You will be expected to explain how you got your answer.

Use a name other than 'guest' and your wins will be recorded.
If enough people are interested we will keep playing with different numbers.
Any questions?
(I have copied this game from the TV show 'Letters and numbers')
Have fun.

(2*100*5)-50-3 = 953

gb4242 · Answer 3 · 2013-12-29T12:18:19

(2*100*5)-50+3 = 953

OOps for previous wrong operator - typo

gb4242:
(2*100*5)-50+3 = 953

Excellent work gb4242 - that's 10 points for you.

My answer was very different so I should be able to have at least 1 more winner!

Melody · Answer 5 · 2013-12-30T09:59:31

No-one else wanted to have a go - that's a little disappointing. (Maybe you did have a go but didn't get an answer. Let me know if this is the case - I'll give you 5 points for trying)
Good work gb4242. (1 win - 10points)

PUZZLE 2
6,2,9,10,50,25
and the magic number is 384

It might be easy, it might be impossible, I haven't even tried to do it yet! (I just wrote the numbers down as i thought of them)
(Added later: I just did it, It might be hard but it is not impossible)

Maybe next time someone else might like to give us the numbers. Maybe the winner?
the rules for the numbers are
There must be 6 number
2 or more of them must be little ones from the set {1,2,3,4,5,6,7,8,9,10}
the remainder must be big ones from the set {25,50,75,100}
You can use the same little number twice if you want to.
I think the magic number should be between 50 and 999 (I think that should work alright)

Happy calculations and good luck.

(If anywone else wants to introduce a different number game I think that would be good)

Melody · Answer 6 · 2013-12-31T12:34:31

6,2,9,10,50,25

This one was hard. That is the way it is sometimes.

Try making 390 and then take away the 6.

If you want more direction then ask for it.

Hi Jedithious,
I haven't seen you about for a while. I am glad that you are back. And that you like this game. I like it too!
And you have posted a great solutions! Yours was a full monty too - you used all the numbers!
I had a different solution.

[ 50 - ( 9+2) ] x 10 - 6 = 384

Hey Jedithious or gb4242,
Do one of you want to offer the numbers for the next round?

Jedithious · Answer 9 · 2013-12-31T03:23:12

Hello Melody,
Yes, I just got back from a long trip. Was missing this place...
Sure, I'd like to offer the numbers. Will I still be able to participate/play, though, for that round?

7, 7, 3, 25, 75, 100 where the magic number is 734

Melody · Answer 10 · 2013-12-31T03:33:00

Hi Jedithious,
I was pondering the same question.
Did you make up the numbers without thinking about the result?
If you did then I think that you could play but maybe you should leave it at least a couple of hours before you post your solution.
Just to let other people have a chance first. Does that sound reasonable?

If anyone would like to voice an objection or an oppinion please do so.
If you do you'll get 5 points for your participation!

p.s. Where did you go? I love travelling!

PUZZLE 3

This is Jedithious's Puzzle and no one has solved it yet!

Jedithious · Answer 11 · 2013-12-31T03:51:40

Hello Melody,
Yes, I just chose the first numbers that came to me.
That sounds reasonable.
Don't you think it would be wonderful if this game could become
like a frequent thing/tradition for this forum?
Its just so snappy, fun, and probably healthy for the brain.

p.s. The beautiful Los Angeles, California

Melody · Answer 12 · 2013-12-31T03:59:45

Yes, but you chose hard numbers! I usually get these pretty easily but I haven't solved this one yet.
Anyway, if no one gets it then the person who makes the closest number wins.

I've never been to the USA, but I think Los Angeles would be beautiful, and a lot of fun. (so long as there wasn't a big earth quake!)

Jedithious · Answer 13 · 2013-12-31T04:23:05

It truly is.
By the way, do you know whether the system you gave to devise numbers and the magic number is flawless? Like are there any possible combinations that won't have an answer (are impossible) or does the system automatically garuntee the perfect playability of any and all possible combinations?

Melody · Answer 14 · 2013-12-31T04:31:05

Most (almost all) have answers, but some don't. I haven't found and answer for this yet. (which is a little unusual)
The nearest that I have so far is 735 (1 too big)
I take it that you haven't found an answer yet?

Jedithious · Answer 15 · 2013-12-31T04:57:11

735 probably wins...
This problem has been tormenting me for the last 15 minutes and I definitely suspect that its one of those impossible combinations.
My suggestion:
Since a combination that is impossible is frustrating and confusing, perhaps the best way to play this would be for the person
who composes the combination to begin with the magic number and then divide, subtract, multiply and/or add numbers backwards
until it equals zero. This way the combination will always be possible and we won't have to worry about nasty impossible ones
creeping up every now and then. Of course that person won't be able to compete, but that's
not really much of a problem at all.

Melody · Answer 16 · 2013-12-31T05:18:29

That would be a really good solution if more people were playing but there are not many people about at the moment.

Maybe if we stick to 4 little ones and 2 big ones they are usually easier. And if I can't do it in 15 or so minutes (that's assuming that i am around) then we move on.
We could try it this way and if it doesn't work then we'll either do it your way or I make up the questions, I wasn't really intending to actually play anyway.

Do you want to do the numbers again? Or maybe just change the 734 to 735. You should mark it clearly as edited (with the reason) in case someone is off trying to do it.

what do you think of that idea?

Kitty, would you like to post the next numbers ?
(You can check it works first if you want to and you can answer yourself if no-one else answers with in 2 hours.)
If you just want to make the numbers up randomly that's fine, I will check them. If they don't work or if I think that they are too difficult I'll change them a little or give a hint. Does that sound alright to you?
If you post the numbers let me know if you have checked them already.
If you want to change to a different game that's okay too. Just tell us what we have to do.

This was a very tricky question
If the number of false statements is 1 then all the others are false which cant be true because only is false so the number of false statements is not 1
If the number of false statements is 2 then 1 the others must also be true but this can't work so the number of false statements is not 2
If the number of false statements is 4 then all are false but the the forth is true - that doesn't work so the number of false statements is not 4
If the number of false statements is 3 then the other 3 statements are all false - good that works. So the number of false statements is 3.
I win!

RE: 5, 3, 3, 10, 25 --magic number 325

I thought there were supposed to be 6 numbers in this game.
Here is an answer
10*(3+3)*5+25 = 325

Melody · Answer 29 · 2014-01-05T04:01:19

Puzzled:
RE: 5, 3, 3, 10, 25 --magic number 325

I thought there were supposed to be 6 numbers in this game.
Here is an answer
10*(3+3)*5+25 = 325

So far we have
25(3+10) = 325 from Warped Tour Girl (I'm really sorry that I left this out before)
and
10*(3+3)*5+25 = 325 from Puzzled
and
(5*10) (3+3) + 25 = 325 from Kitty
Both excellent answers
and mine was different again
I had
5*(3*25 - 10) = 325

I want to talk a little about how you might go about finding these answers.
5, 3, 3, 10, 25 --magic number 325

1)Warped Tour Girl's method maybe
25*4 =100 so 25*12=300 so 25*13=325 (or maybe she just did 325 divided by 25 = 13)
13=10+3
so
25(10+3)=325

2) Kittys method maybe
300+25=325
6*50=300
3+3=6 and 5*10=50
so
(5*10)(3+3)+25=325

3) My method
I know that 25*13=325 (I found that one first)
There is a 5 in the numbers and 5*5=25 so
5*5*13 = 325
but 5*13=65 and 65=75-10 and 3*25=75 so
5*65 -> 5(75-10) -> 5(3*25-10)
so
5(3*25-10) = 325

4) Puzzled might have said 10*(3+3)*5+25 = 325 from Puzzled
325 = 300 +25
300=10*30
30=5*6
6=3+3
so
325 = 10*(3+3)*5 + 25
(changes have been made to Warped Tour Girl's and Kitty's solutions. I'm very sorry for getting solns muddled before. I think it is right now.)
Your question Puzzled - You thought there was supposed to be 6 numbers.
Yes that is what I said originally but it doesn't matter so long as we get a good puzze it just doesn't matter.

RE: 5, 3, 3, 10, 25 --magic number 325

I thought there were supposed to be 6 numbers in this game.
Here is an answer
10*(3+3)*5+25 = 325

So far we have
10*(3+3)*5+25 = 325 from Puzzled
and
(5*10) (3+3) + 25 = 325 from Kitty
Both excellent answers

I want to talk a little about how you might go about finding these answers.
5, 3, 3, 10, 25 --magic number 325

1) Kittys method maybe
100 is divisable by 25 so 325 must be divisable by 25
25 x 13 = 325 and 13=10+3
so
25(10+3)=325.

2) My method
I know that 25*13=325 (I found that one first)
There is a 5 in the numbers and 5*5=25 so
5*5*13 = 325
but 5*13=65 and 65=75-10 and 3*25=75 so
5*65 -> 5(75-10) -> 5(3*25-10)
so
5(3*25-10) = 325

3) Puzzled might have said 10*(3+3)*5+25 = 325 from Puzzled
325 = 300 +25
300=10*30
30=5*6
6=3+3
so
325 = 10*(3+3)*5 + 25

OK gghhhh,
You went all the way back to the first puzzle and found a beautifully simple answer that no one else had found.
Good work. (You also totally confused me, but it doesn't matter)

Puzzle 1: 3,5,7,2,100,50,3 Magic number 953
(2+7)*100+50+3

Now our scores are
gb4242. (1 win - 10points)
Jedithious (1 win- 10 points)
Kitty (2 wins - 20 points)
Warped Tour Girl (2 win - 20 points)
Puzzled (2 wins - 20 points)
gghhhh (1 win - 10 points)
(if there is any errors in the totals let me know and I will try to sort it out)

New puzzle PUZZLE 7
2,6,3,10,50,9 Magic number is 287
HINT: you could try 300-13
You are only allowed to use brackets, +, -, x, and divide.
You can only use the numbers given, you can't use the same number twice but you don't have to use all of the numbers.
The magic number is the total.
If you get the answer try to describe how you worked it out. They are much easier when you start getting some techniques.

From now on, scores will only be given if you solve the most recent puzzle, only because it is just too hard for me to keep track otherwise.
(Except for Puzzle number 3 courtesy of Jedithious, which no one has solved yet. The numbers were 3,7,7,25,75,100 Magic number 734
If you solve this one you can get a great acycolade!)
If you want to offer a new solution to an old problem you are welcome to do that.

Have fun

Puzzled · Answer 43 · 2014-01-09T08:51:13

This is more fun than homework.
I try to find ones that dont need () then do others
I do them with paper then a calculator for the harder answers
I found 17 answers so far.
Here is 7 answers

50*6-10-3 = 287
50*6-10-9/3 = 287
50*(6-2)+10*9-3 = 287
10*(9*2+6)+50-3 = 287
(9*2+6)*10+50-3 = 287
These 2 are neet. same numbers but 1 divides and 1 multiplies just move the )
50*(9-6/2)-10-3 = 287
50*(9-6)*2-10-3 = 287

My friend say he has numbers that only has 1 answer. I dont know how he knows it only has one but I havent found any answers so far and its ben a week. If you want to play with them just tell me and I will list it here maybe you can find the answer.

(Except for Puzzle number 3 courtesy of Jedithious, which no one has solved yet. The numbers were 3,7,7,25,75,100 Magic number 734

I played with this one for a long time and still havent found an answer.
The closest I found is

(100-(25-7)/3)*7+75 = 733 only 1 so far that =733

100*7+25+7+3 = 735
(100*3+75)*7*7/25 = 735 +2 more that = 735

(100-3)*7+75+7-25 = 736
only 1 so far that =736

It mite be like the one my friend gave me that only has one answer. Ill show it to him and see what he says.

They both have the same numbers, but with two different magic numbers

Hi Puzzled
Thanks for that input
I want you to have a go at the logic puzzle on the game site that I posted down the page a bit.
Please tell me if you can get it out.

75,100,8,8,2,1 = 764 <-- but not this one yet

8 x (75+8)+100 = 764
I got this answer quite easily, i will tell you how.
I immediately saw that 8 x 8 = 64 so I needed the 700
8 x 75 = 600 and there is the 100 sitting in the numbers not used yet
so i have
8 x 75 + 8 x 8 + 100 = 764
I can factorise out the 8 to get
8(75+8)+100 = 764

Hey Melody,

An answer to the upper one would be 276 = (9*10+10-8)*3

I think I need an expert opinion to solve the bottom one so I'll leave that open.

Try making 333 with 3 11 22 33 44 55

Walt · Answer 60 · 2014-01-28T12:56:32

(33*11-(55-22))+3=333

Melody · Answer 61 · 2014-01-29T06:16:53

Excellent work Walt and Reinout-g,

I want to take a look at these answers and think about how they may have been done.

First I will look at Reinout-g's
the numbers were
3,8,9,10,10,50 with magic number 276

I can think of 2 different ways that Reinout may have reached this answer.

(1) 3,8,9,10,10,50 with magic number 276
276
= 300 - 24
=3 x 100 - 3 x 8
okay, we only have 1 three so you think that isn't helpful.
Well you are wrong because I am going to factorise out the 3!
You don't need letters to be able to factorise
= 3(100-8)
= 3 x (10 x 10 - 8)
-------------------------------------------------------------------------------------
(2) 3,8,9,10,10,50 with magic number 276
276
I know that 3 goes into 276 because 2+7+6=15 and 3 goes into 15 therefore 3 goes into 276.
(Anyone who has followed the "what a number is divisible by will know this!) therefore
=3 x 92
=3 x (100-8)
=3 x (10 x 10 - 8)

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

Then Reiner left a new one which Walt solved.
3,11,22,33,44,55 with magic number 333
I also got a different solution to WALT so I will show you both. (I am going to do mine first because I thought it was easier.)
But, walt's brain obviously works differently from mine so probably doesn't agree

3,11,22,33,44,55 with magic number 333
(1) 333
= 330 + 3
= 33 x 11 + 3
or
(2) = 33 x (55-44) +3
or
(3) = 33 x (22-11) +3
There are probably other answers along this line as well.
-------------------------------------------------------------------------------------------------------------------
Now lets look at Walt's solution.
3,11,22,33,44,55 with magic number 333
(4) 333
= 330+3 (because we have a 3)
= 33 x 10 + 3 (I have a 33 but not a 10 - umm?) ok lets try
= 33 x 11 - 33 + 3 because I do have an 11.
umm now I don't have two 33s, I can't just factorise out 33 because that will just take me back to the last step. umm- well, -33+3=30 maybe that will help.
= 33 x 11 - 30 I've used the 33 and the 11 so the numbers I have left are 3,22,44,and 55. Umm 55-25=30, and 22+3=25 that's good
= 33 x 11 - (55-25)
= 33 x 11 - (55 -(22+3)) That's right but I suppose I should clean it up a bit.
= 33 x 11 - (55 - 22 -3)
--------------------------------------------------------------------------------------

Actually that is not quite what he was thinking, I just relooked at his answer (33*11-(55-22))+3=333
up to here it is the same
=33 x 11 - 33 + 3 I have used 33 and 11 and 3 so how do I make 33 out of 22,44 and 55. Umm 55-22 = 33
=33 x 11 -(55-22) +3

[size=150]And that is how these can be done. With practice they don't take long, but they can take a long time until you learn some techniques![/size]

EASIER ONE (not done yet)
3,5,2,4 and the magic number is 40

Happy calculations.

My answer is 6*3*(50+6-2)

Even though I cannot be sure whether the last computation is a multiplication, Unless I clearly see the number is not divisible I begin to check whether the number is divisible by any of the given numbers.
so 972/2 = 486, 972/3 = 324, 972/6 = 162

Then I check again with the numbers I have left, beginning with the smallest number (since it seems to be easier to get too)

Then 162/2 = 81, 162/3 = 54, 162/6 = 27

There is no way I can make 27 with the numbers 2,3,8,50
However, for 54 I find 54-50 = 4 and 4 = 6-2
Hence, 972/(6*3) - 50 + 2 - 6

Be aware that my method is a little trial and error.

I tried applying some other methods too such as, trying to find some numbers such that I could get 50*19 or 50*20.
This for instance gave me 50*(8*2+3), however this left me with 972-950 = 22, which I could not solve with only 6 and 6.

You really need to put the 50+8 in brackets because when you get to high school you will learn that multiply is more important than plus, you have to do multiply first.

753 = 50* (8-5) *5 + 1 + 2 or 50*(1+2)*5 + 8 - 5

I will give you my reasoning including the part where I went wrong so it gives an idea on how I approach the puzzle.

Primarly i tried dividing 753 by any of the numbers, which was not possible.

This gave me the hint the final step should be an add or substract operation.

especially when 5 , 25 and 50 are in play, I usually try to get to a multiple of 5 so I tried substracting 8.

This gave me 745 which can be divided only by 5. Then I got 149.

By making some computations I easily realised that I wasn't able to work with 149.

I then started over and this times decided to substract 3 (which is 1+2) to get 750.

I noticed 750 = 50* 5 * 3, and then realised (8-5) would also give me 3.

That's how i came to my answer.

Happy Calculations

I actually remembered an old thread which might really help in these puzzles.

Melody:
Yes, very clever, I like Serena.
now lets see what we have.

Now for the divisability checks. What do we have so far?

1) We have Zamarronics's formula,

2) A number is exactly divisable by 10 if it has a zero at the end. (the last digit is zero)

3) A number is exactly divisable by 2 if it is even.

4) If a number is prime then it is only exactly divisable by 1 and itself

5) A number is exactly divisable by 5 if it ends in 0 or 5

6) A number is exactly divisable by 3 if the sum of its digits is exactly divisable by 3.

7) A number is exactly divisable by 9 if the sum of its digits is exactly divisable by 9

8) If the last 2 digits of a number are a multiple of 4, the whole number is exactly divisible by 4.

9) If the last 3 digits of a number are a multiple of 8, the whole number is exactly divisable by 8.

This is the thread; http://web2.0calc.com/questions/viewtopic.php?f=2&t=7778&p=17858&hilit=number+divisable#p17858

It might help you out to quickly determine whether the number is divisable by any of the numbers.

reinout-g · Answer 86 · 2014-02-26T11:45:32

The answer is (8*2+25)*7+100

I used the same method as always trying to divide the magic number and if it gave no workable solutions then add and substract a little from the number.

This didn't give me much so I then tried working the other way around multiplying 3 and 100 to try and get to 387.
Since it was obvious that the 100 was of no use in multiplications I figured it might be used in a addition or substraction computation.

This gave me the hint towards 287 which brought me back to my original method.
This gave me the division by 7 and finally I tried working my way to the 41 that was left by dividing after some additions and substractions again.

HARD ONE
2,3,8,7,25,100 And the magic number is 387

I had a different method. This is how i did it.
387
=300 + 75 + 12
=3*100+3*25+3*8/2
factor out the 3 and you get
3(100+25+8/2)
Would you like to post the next one reinout? If you would then just copy the question post down and change the numbers for the hard one. Just make sure that it works first. If you don't do it i will do it later. Thanks so much.

Melody:
hi everybody,
Who's up for a challenge? I chose these numbers at random.
PUZZLE 1
3,5,7,2,100,and 50.

Use these numbers to make the number 953.

Rules:
Use only these numbers
No number can be used twice
You do not have to use all the numbers
You can use + - x or divide.
You can use brackets.

First one to respond with exact answer wins. If you post later but you have a substantially different answer, you win too.
If no-one gets the exact answer then closest answer after 12 hours wins. (competition closes in 12 hours)

You will be expected to explain how you got your answer.

Use a name other than 'guest' and your wins will be recorded.
If enough people are interested we will keep playing with different numbers.
Any questions?
(I have copied this game from the TV show 'Letters and numbers')
Have fun.

You can certainly offer the next puzzle - as you have done.

Just make sure that you already know the solution.

If no one answers within a reasonable space of time then you can start giving hints if you want to.

Here is 2 number puzzle for you.

You do not have to use every number but you cannot use any number twice.

You can only use + - x and divide and brackets.

(1) 2,8,25,50,75,100 Magic number is 431 (This one is very hard)

(2) 4,6,25,50,75,100 Magic number is 821 (This one is easier but maybe not super easy )

If we don't have to use every number, here's a solution:

8 (50 + 75/100) + 25 =

400 + 6 + 25 =

431

Melody · Answer 117 · 2014-08-13T06:33:38

An excellent answer Chris!

You do not have to use all the numbers.

One rule which I will never enforce is that at each stage of the calculation the answer is a whole number.

So in the original game 75/100 would not have been accepted as a part of the solution. I'll give you thumbs up anyway but do you want to consider it some more Chris?

Melody · Answer 118 · 2014-08-13T06:35:31

We are still looking for more answers although Chris has found one answer to the first one (there is definitely another answer.)
