What is the Order of Operations in mathematics?

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: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What does the term 'exponent' mean?

Back

An exponent is a number that indicates how many times to multiply the base number by itself. For example, in 9², 9 is the base and 2 is the exponent, meaning 9 is multiplied by itself 2 times (9 x 9).
