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 common acronym to remember this is PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What does PEMDAS stand for?

Back

PEMDAS stands for: P - Parentheses, E - Exponents, MD - Multiplication and Division (from left to right), AS - Addition and Subtraction (from left to right).

Front

Solve: 5 + 2 x 3

Back

11 (First, multiply 2 x 3 = 6, then add 5 + 6 = 11).

Front

Solve: (8 - 3) x 2

Back

10 (First, subtract 8 - 3 = 5, then multiply 5 x 2 = 10).

Front

What is an exponent?

Back

An exponent is a number that shows how many times a base number is multiplied by itself. For example, 5^3 means 5 x 5 x 5.

Front

Solve: 4 x (2 + 3)

Back

20 (First, add 2 + 3 = 5, then multiply 4 x 5 = 20).

Front

What is the result of 6 + 4 x 2?

Back

14 (First, multiply 4 x 2 = 8, then add 6 + 8 = 14).

Front

Solve: 10 - 2 x 3 + 1

Back

5 (First, multiply 2 x 3 = 6, then do 10 - 6 + 1 = 5).

Front

What is the difference between multiplication and addition?

Back

Multiplication is repeated addition. For example, 4 x 3 means adding 4 three times: 4 + 4 + 4 = 12.

Front

Solve: 3 + 5 x (2 + 1)

Back

18 (First, solve inside the parentheses: 2 + 1 = 3, then multiply 5 x 3 = 15, and finally add 3 + 15 = 18).
