Type a full expression like sin(45) + sqrt(2)^3 and press Enter to evaluate it instantly. The calculator respects standard order of operations and right-associative exponents, so results match what you would expect on a physical scientific calculator.
Switch between degrees and radians for trigonometric functions, and use the constants π and e directly in your expressions.
Supported functions
- Trigonometry: sin, cos, tan and inverses (asin, acos, atan)
- Logarithms: log (base 10) and ln (natural)
- Powers, square roots, exponentials and absolute value
- Factorials (n!) and the constants π and e
- Parentheses, percentages and reciprocal (x⁻¹)
