Back

A set of rules that determines the sequence in which calculations are performed in a mathematical expression. The order is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What does the term 'Parentheses' mean in the context of Order of Operations?

Back

Parentheses are symbols used to group parts of a mathematical expression, indicating that the operations within them should be performed first.

What does 'Exponents' refer to in mathematics?

Back

Exponents indicate how many times a number (the base) is multiplied by itself. For example, 4^5 means 4 multiplied by itself 5 times.
