Order of Operations

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

Solve: 3 + 4 x 6 - 4

Back

First step is multiplication: 4 x 6 = 24, then 3 + 24 - 4 = 23.

Front

Evaluate: 5 - (7 + 3) ÷ 2

Back

First solve inside the parentheses: 7 + 3 = 10, then 10 ÷ 2 = 5, so 5 - 5 = 0.

Front

Calculate: 8² + (7 - 4)²

Back

8² = 64, (7 - 4)² = 3² = 9, so 64 + 9 = 73.

Front

What is the result of 6³ - 10 ÷ 5?

Back

6³ = 216, 10 ÷ 5 = 2, so 216 - 2 = 214.

Front

Solve: 3² + 4² - (4 x 2)

Back

3² = 9, 4² = 16, 4 x 2 = 8, so 9 + 16 - 8 = 17.

Front

What is the first operation to perform in the expression 2 + 3 x 4?

Back

The first operation is multiplication: 3 x 4 = 12.

Front

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

Back

First solve inside the parentheses: 5 + 3 = 8, then 8 x 2 = 16.

Front

Evaluate: 10 - 2 x (3 + 1)

Back

First solve inside the parentheses: 3 + 1 = 4, then 2 x 4 = 8, so 10 - 8 = 2.
