How to use the scientific calculator
This is a full-featured online scientific calculator. Tap the keys or type directly into the expression box. Operations follow standard precedence (powers, then × ÷, then + −, with parentheses highest), and exponentiation is right-associative. Trigonometric functions default to degrees and can be switched to radians. Everything is computed locally in your browser.
Frequently Asked Questions
- What functions does this scientific calculator support?
- Arithmetic, parentheses, powers (xⁿ), percent and square roots, plus sin/cos/tan, asin/acos/atan, log (base 10), ln (natural log), and the constants π and e.
- How do I switch between degrees and radians?
- Use the toggle at the top. In Degrees mode sin(30) = 0.5; in Radians mode the same functions use radian inputs.
- Can I type with my keyboard?
- Yes. The expression box accepts direct keyboard input and editing, and you can also tap the on-screen keys. The result previews live — click it to copy.
- What order of operations does it use?
- Standard precedence: powers first, then multiplication and division, then addition and subtraction, with parentheses highest. Exponentiation is right-associative.
