Math Calculators
Scientific Calculator
A free online scientific calculator with parentheses, powers, roots, trigonometry, logarithms, and constants — type or tap expressions.
Quick guide
Type an expression or tap the keypad, using parentheses, powers, roots, trigonometry, logarithms, and constants such as π. Switch between degrees and radians for trigonometric functions, then press equals to evaluate with normal operator precedence.

Supports + − × ÷ ^ %, parentheses, implicit multiplication (2π), sin/cos/tan, ln, log, √, and the constants π and e. Angles use the selected Deg/Rad mode.
How It Works
Type expressions with the keyboard or tap the keypad. It supports operator precedence, parentheses, implicit multiplication (2π, 3(4+1)), powers, roots, trigonometry, and logarithms, with a degrees/radians toggle.
Formula Used
Follows standard order of operations: parentheses → functions → powers → multiply/divide → add/subtract.
Example Calculation
sin(30) + 2^3 × √16 in degree mode evaluates to 0.5 + 8 × 4 = 32.5.
Practical Use Cases
- Evaluate homework expressions step by step.
- Run quick engineering or physics calculations.
- Check trigonometry in degrees or radians.
