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 common acronym to remember this is PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What do brackets (parentheses) indicate in a mathematical expression?

Back

Brackets (or parentheses) indicate that the operations inside them should be performed first before any other operations outside.

Front

What is the first step in solving an expression with brackets?

Back

The first step is to solve any operations inside the brackets.

Front

What is the role of exponents in the Order of Operations?

Back

Exponents are calculated after any operations inside brackets but before multiplication, division, addition, and subtraction.

Front

What should you do if there are multiple operations of the same rank (like addition and subtraction)?

Back

You should perform these operations from left to right.
