What is the order of operations in math?

Back

The order of operations is a set of rules that tells you the correct sequence to evaluate a math expression. It is often remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What does the commutative property of addition state?

Back

The commutative property of addition states that changing the order of the numbers does not change the sum. For example, 3 + 5 = 5 + 3.

What does the commutative property of multiplication state?

Back

The commutative property of multiplication states that changing the order of the numbers does not change the product. For example, 4 x 6 = 6 x 4.

What is the associative property of addition?

Back

The associative property of addition states that the way in which numbers are grouped does not change the sum. For example, (2 + 3) + 4 = 2 + (3 + 4).
