Here is a Order of Operations question that is using the strategy PEMDAS. It is a way to remember the order. I use the sentence Please Excuse My Dear Aunt Sally.

1st: do all operations in the Parenthesis

2nd: Solve all Exponents

3rd: Solve all Multiplications

4th: Solve all Division

5th: Solve all Addition

6th: Solve all Subtraction

(-4)(8-10)= ?

(-6-12)÷3 to the power of 2= ?

-4 times 8=____ next

take that answer and minus -4 times 10

This will give you the first answer...

first subtract -6 minus 12 ( Think of this like money... if you already owe $6 and borrow another $12 then how much are you negative now?)Next take that answer and divide it by 3.

( remember a negative and a positive make a negative)

Next take that answer and when you make it to the power of two you just multiply oit by itself.

(Ex..3 to the power of 2 would be 9.)
