What is the Order of Operations?

Back

The Order of Operations is a set of rules that tells you 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 does PEMDAS stand for?

Back

PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. It is the order in which operations should be performed in a mathematical expression.

Addition. You perform the operation inside the parentheses first.

In the expression 3 + 4 x 6 - 4, which operation do you do first?

Back

Multiplication. According to the order of operations, multiplication is done before addition and subtraction.

26. First, solve the parentheses (6 - 2) = 4, then multiply by 2, and finally add 18.

Identify the error in the calculation: 5 - 3 + 2 = 5 - 5 = 0.

Back

The error is that addition was done first instead of subtraction. According to the order of operations, you should subtract first.

4. According to the order of operations, you multiply first (4 x 2 = 8), then subtract (12 - 8 = 4).

What is a Parenthesis in mathematics?

Back

Parentheses are symbols used to group parts of a mathematical expression. Operations inside parentheses are performed first.
