Ok, I will now admit that I snuck through math in all of my school levels
and now have a problem with an exponent.
The problem reads
(4+1) little 2 for second power x 6-4
The answer I got was 50 but the book answer says 146.
I have to take classes all the way to calculus so watch out...lol
btw...thank you everyone for the kind offers to host my world. A very dear
friend offered and will be hosting it.

AlphaBit,

If I understand the problem correctly, the expression is:

(4+1)^2*6-4

Where the carrot symbol (^) represents "to the power of" and * is
multiplication.

This problem has to do with the order of operations and operator
presidence (or, in computer programming terms "expression evaluation").

To find the correct answer, you have to do each operation in the correct
order.

First, you start by evaluating things inside parenthises. So, you do
4+1, and you get:

(5)^2*6-4

In the order of operations, powers come next. So, take 5 and square it
to get:

25*6-4

In the order of operations, multiplication and division come before
addition and subtraction. So, next you do the multiplication 25*6 to get:

150-4

Subtraction is the only operation left, and you get the book's answer of
146.

Hope that helps...

-Jeremy

4+1=5 x2 =10

Thanks JerMe!
I was doing the obvious. I was taking 6-4 to multiply the 25 by which was
25x2...now I see how it works....thanks soooo much!
I have to warn any of you upcoming students that if at any
time your educational institution wants to let you out of math class to
paint posters for events or work on theatre productions.....DON'T DO IT!:)
