What is the Order of Operations?

Back

The Order of Operations is a set of rules that tells us the correct sequence to evaluate a mathematical expression. The order is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). Often remembered by the acronym PEMDAS.

Back

No

Front

What is the first step in solving the expression 8 + 2 x 5?

Back

You perform the multiplication first: 2 x 5 = 10.

Front

If you have the expression 12 - (3 + 4), what do you do first?

Back

You solve the expression inside the parentheses first: 3 + 4 = 7.

Front

What is the result of 5 + 3 x 2?

Back

11 (because you multiply first: 3 x 2 = 6, then add 5).
