Math Evaluator
What is a Math Evaluator?
Evaluate complex mathematical expressions, scientific functions, and algebraic formulas directly in your web browser. Supports arithmetic operators, trigonometric functions (`sin`, `cos`, `tan`), logarithms (`log`, `ln`), square roots (`sqrt`), powers, and constants (`pi`, `e`).
Why Use This Tool?
- Scientific Calculations: Solve complex mathematical expressions containing nested parentheses and scientific functions.
- Developer Math Testing: Test mathematical equations and expressions before implementing them in application code.
- Safe Evaluation Engine: Safely evaluates math strings without risky JavaScript `eval()` security vulnerabilities.
How to Use
- Type your mathematical expression (e.g. `sqrt(144) + sin(pi / 2) * 5`).
- The evaluator parses operator precedence and scientific functions in real time.
- Copy the calculated numeric result.
Real Working Example
Input:
Expression: 2 * (15 + 5) / sqrt(16) + cos(0)
Output Result:
Evaluated Result: 11.0
Important Technical Details & Formulas
- Math.js AST Parser Engine: Parses mathematical expressions into Abstract Syntax Trees for safe, accurate calculation.
- Supported Functions: `sqrt`, `cbrt`, `abs`, `sin`, `cos`, `tan`, `log`, `log10`, `exp`, `pow`, `factorial`.
- 100% Client-Side Memory: Calculation executes 100% locally in browser memory.

Frequently Asked Questions
How does it handle operator precedence (PEMDAS / BODMAS)?
It evaluates expressions following strict mathematical order of operations: Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.
Can I use trigonometric functions like sin, cos, and tan?
Yes, trigonometric functions accept values in radians or degrees.
Is it safer than JavaScript eval()?
Yes, it uses a dedicated math parser that executes no arbitrary code, preventing security vulnerabilities.
Does it support math constants like pi and e?
Yes, built-in constants pi (3.14159...) and e (2.71828...) are supported.
Is it free?
Yes, 100% free with unlimited calculations.
