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).

Solve: 3 + 5 × 2

Back

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

Front

Solve: (4 + 6) × 2

Back

20 (First, add 4 + 6 = 10, then multiply by 2).

Front

What should you do first in the expression: 8 - 3 + 2?

Back

Perform addition and subtraction from left to right.

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 + 2) - 4?

Back

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

Front

Solve: 7 + 2 × 3 - 1

Back

12 (First, multiply 2 × 3 = 6, then add 7 + 6 = 13, and finally subtract 1).

Front

What is the value of x in: 2x + 3 = 11?

Back

4 (First, subtract 3 from both sides to get 2x = 8, then divide by 2).

Front

Solve: 9 - (3 × 2) + 4

Back

7 (First, multiply 3 × 2 = 6, then subtract 9 - 6 = 3, and finally add 4).
