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: (6 + 2) × 3

Back

24 (First add 6 + 2 = 8, then multiply by 3.)

Front

What is the value of 9 - 3 × 2 + 1?

Back

4 (First multiply 3 × 2 = 6, then 9 - 6 + 1 = 4.)

Front

True or False? 5 + 2 × (3 + 1) = 13

Back

True (First calculate inside the parentheses: 3 + 1 = 4, then 2 × 4 = 8, and finally 5 + 8 = 13.)

Front

What is the first step in solving 4 + (6 - 2) × 5?

Back

Calculate inside the parentheses: 6 - 2 = 4.

Front

Solve: 8 ÷ 2 + 3 × 4

Back

20 (First divide: 8 ÷ 2 = 4, then multiply: 3 × 4 = 12, and finally add: 4 + 12 = 16.)

Front

What is the result of 7 + 2 × 3 - 1?

Back

12 (First multiply: 2 × 3 = 6, then add and subtract: 7 + 6 - 1 = 12.)

Front

Solve: 10 - 2 × (3 + 4)

Back

-4 (First calculate inside the parentheses: 3 + 4 = 7, then multiply: 2 × 7 = 14, and finally subtract: 10 - 14 = -4.)
