HARD ONE
2,5,5,6,8,10 and the magic number is 97

FINALLY got this after awhile :D
gb4242:(2*100*5)-50+3 = 953
OOps for previous wrong operator - typo
Jedithious:(9*50) - (2*25) - 10 - 6 = 384
I really like this game.
kitty<3:Sure, I checked these already:
Thanks Kitty.
PUZZLE 5
5, 3, 3, 10, 25 --magic number 325
You have to use the numbers (not necessarily all of them) to make the magic number 325.
You are allowed to use + - x and divide and you can use brackets
I have found 2 answers, and there might be more. If you can find 1 of them why don't you post it and show us how clever you are.
I would really like to get some games like this going, but I need people to join in!

Do you know of any other ways?
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
Melody: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
Melody:*
5, 9, 7, 8, 25, 75 Magic number 894
Puzzled's solution
(75-7)*8+25*(9+5)=894
That is an excellent solution puzzled!
Puzzled says that she has found 3 more solutions.
Puzzled is really good at this!
Now our scores are
gb4242. (1 win - 10points)
Jedithious (1 win- 10 points)
Kitty (2 wins - 20 points)
Warped Tour Girl (1 win - 10 points) (I'm sorry I left you out before)
Puzzled (2 wins - 20 points)
Come on people - please play this game with us.
Lets see if we can find another of those solutions that puzzled says exist!
I know one.
[size=150]I'll give you a hint[/size]
These are the numbers
5, 9, 7, 8, 25, 75 Magic number 894
now I noticed that 894=900-6
900 is pretty easy to get with 9,25,and 75
6 is maybe a little more tricky but you can get it with 5,7 and 8
Now someone should give this a try.
You can post even if you can only do half of it. or even just show us what you have thought about
We just want you to join in
jazz:I've tried ... I can't get to 734.
Here's the closest I got.
(100 + 3 + (75/25))*7 -7 = 735

bump?

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.
reinout-g: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.
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.

Answers are here
http://web2.0calc.com/questions/using-1-2-3-4-how-do-you-get-22
What about 1,3,9,10,12 to -9?
Every number can only be used once and(unless you can find a different solution) all numbers are used.
What about 1,3,9,10,12 to -9?
Every number can only be used once and(unless you can find a different solution) all numbers are used.
So....you want to make -9 ???
(3 - 12) + (10 - 9) - 1 =
-9 + 1 - 1 =
-9 + 0 =
-9
The last one posted by Melody is 4x3x2-(1x2).
Working:
4x3=12
12x2=24
1x2=2
24-2=22
Is this your number puzzle (is it just +-x and divide and are you sure it is doable)
If this is correct then you do not need to reply- not until you want to answer anyway
6,6,12,35,38,66,104. Magic number is -912
Anonymous: "Sorry 6,6,12,35,38,66,104."
This was very difficult, but I finally got it after so long!
( -104 + 66 + 35 + (6/6) ) * 12 * 38
If I could contribute a puzzle?
The numbers are 2 6 17 21 23 85 and the Magic Number is 815. :mrgreen:
Excellent solution Pokemonfan58!
I'm impressed.
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.
(especially if people ask for hints)
Thank you.
Melody.

what a show off Chris,
okay reinout,
you are looking for something to do. We need a new number puzzle. ta.
Ah, M'lady doth not appreciate the craft and skill of one so humble as myself ???..........Sisyphus himself was so over-awed by such display of number manipulation that even he took brief reprise from his unending duties to pay homage to CPhill !!!

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 )

(1) 2,8,25,50,75,100 Magic number is 431 (This one is very hard)
If we don't have to use every number, here's a solution:
8 (50 + 75/100) + 25 =
400 + 6 + 25 =
431
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?
We are still looking for more answers although Chris has found one answer to the first one (there is definitely another answer.)
