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

Why is it important to follow the Order of Operations?

Back

Following the Order of Operations ensures that everyone calculates expressions in the same way, leading to consistent and correct results.

Front

What is the result of 3 + 5 × 2?

Back

13 (Multiplication is done before addition).

Front

What is the result of (4 + 2) × 3?

Back

18 (Parentheses are evaluated first).

Front

Explain the error: 5 - 3 + 2 = 5 - 5 = 0

Back

The error is that addition was done before subtraction; according to the Order of Operations, subtraction should be performed first.
