How it works
Write an expression and press =. The calculator handles brackets and order of operations itself (powers first, then × ÷, then + −) — no extra steps needed.
- Example 1:
2 + 3 * 4= 14 (first 3 × 4 = 12, then + 2). - Example 2: in DEG mode
sin(90)= 1. Keep DEG if your angle is in degrees; switch to RAD with the DEG button for radians. - Example 3:
2^10= 1,024 and5!= 120. - Keyboard: type numbers and + − * / ^ directly, Enter = equals, Backspace = delete one character, Escape = clear.
Note: log means log base 10, ln is the natural log. % divides a number by 100 — for example 50% = 0.5.
How to use
- Click the calculator buttons or type numbers and operators directly with your keyboard.
- Press = (or Enter) for the answer; use the DEG button to switch between degrees and radians for angles.
- Click any entry in the history list to reuse that result in a new calculation.
