Simplify each pair of expressions.

1. 36 - 8 ÷ 2

(36 - 8) ÷ 2

There are several problems like the one above. Under the same set of directions, though, some problems look like this :

7. 3(9+2) - 8

__________

7

With only one problem.

So, what am I supposed to do?

Evaluate each expression for a = 3, b= 7, c = 4.

13. a(2b-c)

?

Does evaluate just mean...Answer?

**Eve**, Sunday, August 31, 2008 at 6:57pmI believe that I understand the directions, now. Thank you though. It'd odd - Jiskha homework help used to work so much more quickly, in past years. I wonder what happened. Anyways, thanks again, and good luck with the other questions.

**bobpursley**, Sunday, August 31, 2008 at 7:29pmUnder the first two, do the operations in the correct order: Parentheisis, multiply, divide, add subtrract.

So on the first

36 - 8 ÷ 2, do the divide first:

36-4 then the subtract.

This will be a quite a different answer from the second.

Yes, on the last, it means evaluate.
