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

Solve: 3 + 5 × 2

Back

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

Front

Solve: (8 + 2) × 3

Back

30 (First, add 8 + 2 = 10, then multiply by 3.)

Front

What is the first step in the Order of Operations?

Back

Perform calculations inside Parentheses.

Front

Solve: 12 ÷ (2 + 4)

Back

2 (First, add 2 + 4 = 6, then divide 12 by 6.)

Front

What is the result of 5 + 3 × 4 - 2?

Back

15 (First, multiply 3 × 4 = 12, then add 5 and subtract 2.)

Front

Solve: 10 - 3 + 2 × 5

Back

15 (First, multiply 2 × 5 = 10, then subtract 3 from 10 and add 10.)

Front

What is the role of Exponents in the Order of Operations?

Back

Exponents are calculated after Parentheses and before Multiplication and Division.

Front

Solve: 6 + 2 × (3 + 1)

Back

14 (First, calculate inside the parentheses: 3 + 1 = 4, then multiply 2 × 4 = 8, and finally add 6.)
