The remainder is 1   NOT 3

10 divided by 3 = 3 remainder 1

so  10mod3 = 1

You can put it into the calc just like this:

mod(10,3)=

mod(10,3) = 1

Hi Ginger :)

I have no idea what you are talking about.

Can you explain the problem better?

127000*3 = 381000

It is the 2nd button at the top left.

Thank you very much, Alan.

We want to use a process by which we keep dividing until we have a "0"  whole number 

First, divide 105 by 5  and we have

105 /  5   =   21  whole number   and   0  remainder

Now,  divide  21 by 5

21 / 5   =   4 whole number  and 1 remainder

Now....divide  4  by 5

4 / 5  =   0 whole number   and   4  remiander

Read the remainders from  bottom  to  top  =     410

And this is the  base 5 representation of 105  =  410₅

a + b + c = 6 →  b + c  = 6 - a     (1)

ac + ab + bc  = 5  →  a ( b + c)  =  5 - bc     (2)

abc  = -12   →  bc = -12/a      (3)

Put (1)  and (3)  into (2)

a ( 6 - a) =  5 - (-12/a)

6a - a^2 =  5 + 12/a       multiply through by a

6a^2 - a^3  =  5a +  12      rearrange as

a^3 - 6a^2 +  5a +  12   =  0

Using the Rational Zeroes  Theorem, 3  is shown to be a root

Using synthetic division, we can find the remaining polynomial

3  [   1      -  6      5       12 ]

                   3    - 9      -12

       _________________

       1       - 3      -4       0

The remaining polynomial   is

a^2  - 3a  - 4

The zeroes of this are

(a - 4) (a + 1)  = 0    

4   and   -1

So...."a"  can arbitrarily  be either  3, 4  or -1

If we assign  "a" as  4,  "b"  and  "c"  can  be assigned as 4  and -1  respectively

And   a^3  +  b^3  + c^3  =    3^3 + 4^3 + (-1)^3  =  27 + 64 - 1  =  90

e^z = 1 + z + z²/2! + z³ /3! + z⁴/4! + ...

e^-z = 1 - z + z²/2 - z³/3! + z⁴/4! - ...

So (e^z + e^-z)/2 = 1 + z²/2! + z⁴/4! + ...

.

4*5^2 + 1*5^1 + 0*5^0 = 105, so 410₅ = 105₁₀

Anchor Anna and Bob in any two chairs.....and they can be seated in two ways.....the other seven people can be arranged in 7!  = 5040 ways

So....

2 ways x 5040 ways   =  

10,080  arrangements

"Of"  usually means "multiply"

So.....66%  of 500   means that we convert the %  to a decimal and multiply 

So....

66% of 500  = 

.66 x 500  =

330

Solve for a, b, c

a = -1, a =3, a = 4

b = -1, b =3, b = 4

c = -1, c =3, c = 4

You can the values that balance your equations and cube them to get what you want.

2 x 23 x 5 to the 2nd power is 1150

What you say is very true. Unfortunately, I never learned how to control sunshine very well, but I am a near expert at throwing barbs. Perhaps I could learn from you. You seem wise beyond your years.  You are also very good at teaching math to the dumb and brain-dead (young and old, if you prefer). I know this to be a fact, because I’ve learned much from your posts.  

Is that really true though? From what I've seen, barbs don't do that good a job at piercing fog.....but shining some warm sunshine on that fog is what really clears it up........ 

We want to be grateful to Melody!

A rude comment with sharp barbs can pierce the ditzy fog that sometimes envelopes intelligent persons.  It’s probably better not to totally ignore these, just ignore the rudeness. Perhaps then someone that’s too hot 2 die will not be too dumb 2 live.     

2m+8+m=143

Combine the "m" and subtract the 8 (on both sides)

3m = 135

Divide by 3

m=45

If you weigh 100 pounds...

100 pounds = 45.359 kg

Say you go to the gym and use the stairstepper where each step is roughly 18 centimeters.

45.359(9.8)(.18) = 80.013276 W = 80.013276 J

Now say you use the stairstepper for an hour with one step per second

80.013276(3600) = 288,047.79 J

Now convert from Joules to Food Calories (Don't be confused when looking at nutrition facts... 1 food calorie is a kilocalorie)

288,047.79/4186 = 68.81 Calories are burned per hour

To burn 100 calories you would have to use the stairstepper for roughly 87 minutes..

Note: this is assuming you can continously workout on the stairstepper with one step per second.

none, you don't have to work out at all especally if you weigh 100 pounds

I like my answer better Chris. 

If the person needed more help I invited them to ask.

The person didn't ask so they must have been happy with my directions. :)

no, how you can find out if it's a multiple of three easly is 

1. you add the digits up (like for instince 121 1+2+1=4)

2. repeat step one till you have a single digit number

3. if the number is 3,6, or 9 then it's a multiple of three

keep in mind this only works for 3 though if you do this and the final number is 9 then it's a multiple of 9, if the begining number is even and it and the final number is 3, 6, or 9 then it's a multiple of 6 and if it doesn't work out then it's a multiple of 1  (this doesn't work for fractions, decimals, negetive numbers, and imagenary numbers)

first do the parenthesis

43*3*65-2*3*443*5-265-2*4-14

then multiplecation

8385-13290-265-8-14

then subtraction (from left to right)

-4905-265-8-14

-5170-8-14

-5178-14

-5192
