Order of Operations

Front

What is the Order of Operations?

Back

A set of rules that determines the correct sequence to evaluate a mathematical expression. The order is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What does PEMDAS stand for?

Back

PEMDAS is an acronym for Parentheses, Exponents, Multiplication and Division, Addition and Subtraction, which helps remember the order of operations.

Front

Evaluate: 3 + 5 × 2

Back

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

Front

Evaluate: (8 - 3) × 2

Back

10 (First, subtract 8 - 3 = 5, then multiply by 2.)

Front

What is the first step in the Order of Operations?

Back

The first step is to evaluate expressions inside Parentheses.

Front

Evaluate: 6 + (4 × 3)

Back

18 (First, multiply 4 × 3 = 12, then add 6.)

Front

What is an exponent?

Back

An exponent is a number that shows how many times to use the base in a multiplication. For example, 2² means 2 × 2.

Front

Evaluate: 2³ + 4

Back

12 (First, calculate 2³ = 8, then add 4.)

Front

Evaluate: 10 - (2 + 3) × 2

Back

0 (First, calculate (2 + 3) = 5, then multiply by 2 = 10, and finally subtract from 10.)

Front

What is the result of 15 ÷ 3² + 9 ÷ 3?

Back

28 (First, calculate 3² = 9, then 15 ÷ 9 = 1.67, and 9 ÷ 3 = 3, finally add them.)
