What is the Order of Operations?

Back

The Order of Operations is a set of rules that determines the sequence in which calculations are performed in a mathematical expression. The order is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). Often remembered by the acronym PEMDAS.

What does PEMDAS stand for?

Back

PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). It is a mnemonic to remember the order of operations.

Front

Calculate: 3 + 5 × 2

Back

According to the order of operations, you should first perform the multiplication: 5 × 2 = 10, then add 3: 3 + 10 = 13.

Front

Calculate: (4 + 6) × 2

Back

First, solve the expression in parentheses: 4 + 6 = 10, then multiply by 2: 10 × 2 = 20.

What is the value of 5^3?

Back

5^3 means 5 multiplied by itself three times: 5 × 5 × 5 = 125.

Front

What is the value of 2^4?

Back

2^4 means 2 multiplied by itself four times: 2 × 2 × 2 × 2 = 16.

Front

Evaluate: 8 - 3 + 2

Back

According to the order of operations, perform addition and subtraction from left to right: 8 - 3 = 5, then 5 + 2 = 7.

Front

Evaluate: 6 + (2 × 3)

Back

First, solve the expression in parentheses: 2 × 3 = 6, then add 6: 6 + 6 = 12.

Front

What is the value of 9 + (12 - 10)?

Back

First, solve the expression in parentheses: 12 - 10 = 2, then add 9: 9 + 2 = 11.
