Flashcard 18 - Mathematics: Quantitative Reasoning Flashcard Set for the TSIA2

Back

The correct answer is:

Evaluate the exponent \(2^{3}\).


Explanation:

When an expression has a variety of operations, we have to follow the order of operations rule to get the correct answer.

Do everything in parentheses (P), left to right.
Evaluate any exponents (E), left to right.
Do all multiplication and division (MD), in order, left to right.
Finally, do all addition and subtraction (AS), in order, from left to right.

A good way to remember: “Please Excuse My Dear Aunt Sally.”

Since there aren’t any parentheses to deal with, we evaluate the exponent (next order of operation) \(2^{3}\) first.
