Order of Operations

Front

What is the Order of Operations?

Back

A set of rules that determines the sequence in which calculations are performed in a mathematical expression.

Front

What does PEMDAS stand for?

Back

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

Front

Calculate: 3 + 5 × 2

Back

13 (First, multiply 5 × 2 = 10, then add 3.)

Front

Calculate: (8 - 3) × 4

Back

20 (First, subtract 8 - 3 = 5, then multiply by 4.)

Front

What is the first step in the Order of Operations?

Back

Perform calculations inside Parentheses.

Front

Calculate: 10 - 2 + 6

Back

14 (Perform addition and subtraction from left to right.)

Front

Calculate: 12 ÷ 4 + 3 × 2

Back

9 (First, divide 12 ÷ 4 = 3, then multiply 3 × 2 = 6, and finally add 3 + 6 = 9.)

Front

What is the result of 5 + (3 × 2) - 4?

Back

7 (First, multiply 3 × 2 = 6, then add 5 + 6 = 11, and finally subtract 4.)

Front

Calculate: 7 + 2 × (3 + 1)

Back

15 (First, calculate inside the parentheses: 3 + 1 = 4, then multiply: 2 × 4 = 8, and finally add: 7 + 8 = 15.)

Front

What is the importance of the Order of Operations?

Back

It ensures that everyone calculates expressions in the same way, leading to consistent results.
