Order of Operations

Front

What is the Order of Operations?

Back

A set of rules that tells us the correct sequence to evaluate 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

Evaluate: 3 + 4 x 2

Back

11 (First, multiply 4 x 2 = 8, then add 3).

Front

Evaluate: (8 - 3) + 2 x 5

Back

10 (First, calculate inside the parentheses: 8 - 3 = 5, then 2 x 5 = 10, finally 5 + 10 = 15).

Front

What operation do you perform first in 6 + 2 x 3?

Back

Multiplication (2 x 3 = 6, then add 6 + 6 = 12).

Front

Evaluate: 10 - 4 ÷ 2

Back

8 (First, divide 4 ÷ 2 = 2, then subtract 10 - 2 = 8).

Front

What is the result of 5 x (2 + 3)?

Back

25 (First, calculate inside the parentheses: 2 + 3 = 5, then multiply 5 x 5 = 25).

Front

Evaluate: (12 ÷ 4) + 3 x 2

Back

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

Front

What is the first step in solving 7 + (3 x 2)?

Back

Calculate inside the parentheses (3 x 2 = 6, then add 7 + 6 = 13).

Front

Evaluate: 15 - (3 + 2) x 2

Back

5 (First, calculate inside the parentheses: 3 + 2 = 5, then multiply 5 x 2 = 10, finally 15 - 10 = 5).
