Math: Order of Operations

16....According to PEMDAS, you do what is in parentheses first. So also according to PEMDAS, multiplication comes first so 2 times 2 is 4 and you take 4 from 8 to give you 4. So after that you do the next step in PEMDAS which is the exponents. You multiply 4 by itself and get 16

"(8 - 2 * 2) ^ 2"

4....According to PEMDAS, Subtraction comes first (10-8=2), then add 2 and 2 to get your answer

"10 - 8 + 2"

5....According to PEMDAS, 10\2 is 5 so you leave that alone for now and subtract 7 from 17 which gives you 10 and then you subtract 5 from 10 to give you 5.

"17 - 7 - 10 / 2"

9....According to PEMDAS, Division comes first so 10 / 2 = 10, next we subtract. And 10-1 = 9 which is our final answer.

"20 / 2 - 1"

TRUE...do the parentheses and exponents as the come first, then do whichever comes first between division and multiplication/ addition and subtraction
