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).

Solve: 3 + 4 x 6 - 4

Back

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

Front

What is the first step in solving: 8 + 2 x (3 - 1)?

Back

First step is to solve the parentheses: 3 - 1 = 2.

Front

Solve: 75 ÷ 5 × 9 – 9

Back

First, divide: 75 ÷ 5 = 15, then multiply: 15 x 9 = 135, finally subtract: 135 - 9 = 126.

Front

What is the value of: 8 ÷ 4 + 2 x 3?

Back

First, divide: 8 ÷ 4 = 2, then multiply: 2 x 3 = 6, finally add: 2 + 6 = 8.

Front

Solve: -2 x (3 + 8 ÷ 4)²

Back

First, solve inside the parentheses: 8 ÷ 4 = 2, then (3 + 2)² = 5² = 25, finally -2 x 25 = -50.

Front

What is the result of: 4 + 9 + 8 ÷ 4?

Back

First, divide: 8 ÷ 4 = 2, then add: 4 + 9 + 2 = 15.

Front

What is the importance of parentheses in order of operations?

Back

Parentheses indicate which operations should be performed first, altering the standard order of operations.

Front

What is an exponent?

Back

An exponent indicates how many times a number (the base) is multiplied by itself.
