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

What is the result of 8 - 3 + 2?

Back

The result is 7, calculated from left to right.

Front

What does 'exponents' refer to in the order of operations?

Back

Exponents indicate how many times a number (the base) is multiplied by itself, such as in 2^3 = 2 x 2 x 2 = 8.

Front

How do you handle multiplication and division in the order of operations?

Back

Multiplication and division are performed from left to right, whichever comes first.
