Formula

The Order of Operations (PEMDAS) is a set of rules that dictate the sequence in which operations are performed in a mathematical expression: Parentheses, Exponents, Multiplication and Division (left to right), Addition and Subtraction (left to right).

PEMDAS: ( ) → ^ → ×/ → +/ −

Percentage: The percentage value you want to apply

Number: The original number or value

Result: The calculated result

How It Works

1Enter a mathematical expression using +, -, *, /, parentheses, and numbers.
2Click Calculate to evaluate following PEMDAS rules.
3The result shows the final computed value.

Examples

Evaluate 3 + 5 × (2 - 8) ÷ 2

1.Parentheses first: (2 - 8) = -6
2.Expression becomes: 3 + 5 × (-6) ÷ 2
3.Multiplication and division left to right: 5 × (-6) = -30
4.Then: -30 ÷ 2 = -15
5.Addition: 3 + (-15) = -12

Result: -12

Frequently Asked Questions

PEMDAS stands for Parentheses, Exponents, Multiplication and Division (left to right), Addition and Subtraction (left to right). It's the standard order of operations in mathematics.

Yes! Use the ** operator for exponents (e.g., 2 ** 3 for 2³). The calculator evaluates exponents after parentheses.
