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 x 2

Back

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

Front

Solve: (8 - 3) x 4

Back

20 (First, subtract 8 - 3 = 5, then multiply by 4).

Front

What should you solve first in the expression: 6 + 2 x (3 + 1)?

Back

The expression inside the parentheses: (3 + 1) = 4.

Front

Solve: 10 - 2^3 + 5

Back

3 (First, calculate 2^3 = 8, then 10 - 8 + 5 = 7.)

Front

What is the result of 12 ÷ 4 x 3?

Back

9 (First, divide 12 ÷ 4 = 3, then multiply by 3).

Front

Solve: 5 + 3 x (2 + 4) - 1

Back

20 (First, solve inside the parentheses: (2 + 4) = 6, then 3 x 6 = 18, finally 5 + 18 - 1 = 22).

Front

What is the value of 7 + 2 x 5 - 3?

Back

14 (First, multiply 2 x 5 = 10, then 7 + 10 - 3 = 14).

Front

Solve: 15 - (3 x 2) + 4

Back

13 (First, calculate inside the parentheses: 3 x 2 = 6, then 15 - 6 + 4 = 13).
