Basic Calculator
Perform basic arithmetic operations including addition, subtraction, multiplication, and division.
A basic math calculator evaluates arithmetic expressions with support for order of operations, parentheses, and exponents.
Examples
Simple arithmetic
With parentheses
Exponents
Frequently Asked Questions
What operators are supported?
Does it follow order of operations?
Can I use parentheses?
Quick Tips
- •Double-check your inputs — small errors lead to incorrect results.
- •Use parentheses to explicitly control the order of operations.
- •Use the ^ operator for exponents and % for modulo (remainder).
A basic math calculator evaluates arithmetic expressions with support for order of operations, parentheses, and exponents.
How to Use This Calculator
Enter a mathematical expression using numbers and operators (+, -, *, /, ^, %). Use parentheses to control the order of operations. The calculator will evaluate the expression step by step.
Understanding the Formula
Standard order of operations (PEMDAS): Parentheses, Exponents, Multiplication/Division (left to right), Addition/Subtraction (left to right).
Examples
Simple arithmetic
2 + 3 * 4 = 14 (multiplication before addition)
With parentheses
(2 + 3) * 4 = 20 (parentheses first)
Exponents
2 ^ 3 + 1 = 9 (2 cubed plus 1)
Frequently Asked Questions
What operators are supported?
Addition (+), subtraction (-), multiplication (*), division (/), exponentiation (^), and modulo (%).
Does it follow order of operations?
Yes, the calculator follows PEMDAS/BODMAS rules automatically.
Can I use parentheses?
Yes, use parentheses to group operations and override default precedence.
Assumptions & Limitations
- Assumes valid mathematical expressions with balanced parentheses.
- Assumes exact input values; rounding in inputs propagates to results.
- Results may show floating-point approximations for irrational numbers.
