What is the Order of Operations?

Back

The Order of Operations is a set of rules that determines the correct sequence to evaluate 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.

Back

6(8) means 6 multiplied by 8, which equals 48.

Front

What is an exponent?

Back

An exponent is a number that shows how many times to use the base in a multiplication. For example, in 5^3, 5 is the base and 3 is the exponent, meaning 5 x 5 x 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

What is the result of 2 + 3 x 4?

Back

According to the Order of Operations, you first multiply 3 by 4 to get 12, then add 2 to get 14.

What does 'parentheses' mean in math?

Back

Parentheses are symbols used to group numbers or variables together. Operations inside parentheses are performed first according to the Order of Operations.
