What is the Order of Operations?

Back

The Order of Operations is a set of rules that determines the sequence in which calculations are performed in a mathematical expression. The acronym PEMDAS is often used to remember the order: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Which operation do you perform first in the expression 3 + 5 × 2?

Back

You perform multiplication first, so 5 × 2 = 10, then add 3 to get 13.

Front

True or False: You always add before you subtract in the Order of Operations.

Back

False. You perform addition and subtraction from left to right.

What is the commutative property of multiplication?

Back

The commutative property of multiplication states that changing the order of the factors does not change the product. For example, 5 × 4 = 4 × 5.
