order of operation practice

Front

What is the order of operations in mathematics?

Back

The order of operations is a set of rules that determines the sequence in which calculations are performed. The common acronym is PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What operation should you perform first in the expression (12 + 10) ÷ 10 x 14 - 6?

Back

Addition should be performed first, resulting in (22) ÷ 10 x 14 - 6.

If you have the expression 8 - 3 + 2, what is the correct order of operations?

Back

You perform addition and subtraction from left to right, so 8 - 3 = 5, then 5 + 2 = 7.
