What is آلة حاسبة?

A tool for evaluating math expressions directly. Supports arithmetic operations plus trigonometric functions, logarithms, exponents, and mathematical constants (pi, e). Maintains a calculation history.

How to Use

1. Enter a math expression (e.g., 2+3*4, sin(pi/2)).
2. Press Enter to see the result.
3. View previous calculations in the history.
4. Click 'Clear History' to reset.

Key Features

• Arithmetic operations with parentheses
• Trigonometric functions (sin, cos, tan), logarithms (log, ln)
• Built-in math constants (pi, e)
• Calculation history retention

Tips

• Use * for multiplication, / for division, and ** for exponentiation.
• pi equals 3.14159..., e equals 2.71828... as mathematical constants.
• Use parentheses to explicitly set operation order in complex expressions.
