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 acronym PEMDAS helps remember the order: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Front

Why do we use parentheses in calculations?

Back

Parentheses indicate which operations should be performed first, helping to clarify the order of operations.

Front

What is the result of 3 + 5 x 2?

Back

13 (because multiplication is done before addition).

Front

What is the result of (4 + 2) x 3?

Back

18 (because the operation inside the parentheses is done first).
