What is the Order of Operations?

Back

The Order of Operations is a set of rules that tells us 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.

What is a Parenthesis in math?

Back

Parentheses are symbols used to group numbers or variables together in a mathematical expression, indicating that the operations inside should be performed first.

Front

What is Multiplication?

Back

Multiplication is a mathematical operation that represents the repeated addition of a number. For example, 3 x 4 means adding 3 four times (3 + 3 + 3 + 3 = 12).

Front

What is Division?

Back

Division is a mathematical operation that represents the process of splitting a number into equal parts. For example, 12 ÷ 4 means splitting 12 into 4 equal parts, which equals 3.
