Evaluate The Following Expression Calculator

Reviewed by Calculator Editorial Team

This calculator evaluates mathematical expressions with support for basic arithmetic, parentheses, and common mathematical functions. It's perfect for students, engineers, and anyone needing to quickly compute complex expressions.

How to Use This Calculator

Enter your mathematical expression in the input field and click "Calculate". The calculator will evaluate the expression and display the result.

Tip: Use parentheses to control the order of operations. For example, (2 + 3) * 4 evaluates to 20, while 2 + 3 * 4 evaluates to 14.

Supported Mathematical Operations

The calculator supports the following operations:

  • Basic arithmetic: +, -, *, /, ^ (exponentiation)
  • Parentheses for grouping: ( )
  • Common mathematical functions: sqrt(), pow(), abs(), sin(), cos(), tan(), log(), ln()
  • Constants: pi, e

Example expression: sqrt(pow(3, 2) + pow(4, 2))

This evaluates to 5 because 3² + 4² = 9 + 16 = 25, and the square root of 25 is 5.

Examples of Expressions

Here are some example expressions and their results:

  • 2 + 3 * 4 → 14
  • (2 + 3) * 4 → 20
  • sqrt(25) → 5
  • pow(2, 3) → 8
  • sin(pi/2) → 1
  • log(100) → 2 (base 10 logarithm)

Limitations and Notes

The calculator has the following limitations:

  • Does not support matrix operations
  • Does not support variables or equations
  • Does not support complex numbers
  • May have precision limitations with very large or very small numbers

For advanced mathematical operations, consider using specialized software like Mathematica, MATLAB, or Wolfram Alpha.
