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.

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 + 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

Which operation do you perform first in 6 + 2 × 3?

Back

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

Front

Evaluate: 12 ÷ (2 + 4)

Back

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

Front

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

Back

21 (First, add 3 + 2 = 5, then multiply 5 × 5 = 25, and finally subtract 4.)

Front

Evaluate: 10 - 2 × 3 + 1

Back

5 (First, multiply 2 × 3 = 6, then subtract 10 - 6 = 4, and finally add 1.)

Front

What is the first step in solving 15 - 3 ÷ 1?

Back

Division (3 ÷ 1 = 3, then subtract 15 - 3 = 12.)

Front

Evaluate: (4 + 6) ÷ 2 × 5

Back

25 (First, add 4 + 6 = 10, then divide 10 ÷ 2 = 5, and finally multiply by 5.)
