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

  1. Type your mathematical expression (e.g. `sqrt(144) + sin(pi / 2) * 5`).
  2. The evaluator parses operator precedence and scientific functions in real time.
  3. 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.
