Scientific Calculator
A full scientific calculator in your browser — trig, logs, powers, roots, factorials and constants, with degrees/radians and keyboard input.
Using the scientific calculator
Build an expression with the keypad or your keyboard and the result
previews live below it; press = (or Enter) to commit it.
Functions like sin(, log( and √(
open a parenthesis for you — just type the value and close it. Use
^ for powers, ! for factorials and the
Degrees toggle to switch the angle mode for trigonometry.
What it supports
- Arithmetic: + − × ÷ %, with correct order of operations.
- Powers & roots: xʸ and √, plus exp.
- Trigonometry: sin, cos, tan and inverses, in degrees or radians.
- Logarithms: natural log (ln) and base-10 log.
- Constants: π and e.
- Factorials: n! for non-negative integers.
Keyboard shortcuts
- 0–9 . ( ) + − * / ^ % — type directly.
- Enter or = — evaluate.
- Backspace — delete the last character.
- Esc — clear everything.
Frequently asked questions
What can this scientific calculator do?
It handles the four basic operations plus powers (^), roots, percentages, factorials (!), trigonometry (sin, cos, tan and their inverses), logarithms (ln and log), exponentials and the constants π and e — with full parentheses support.
How do I switch between degrees and radians?
Use the Degrees toggle above the keypad. When it's on, trigonometric functions interpret and return angles in degrees; turn it off for radians.
Can I type with my keyboard?
Yes. Numbers, operators and parentheses work directly, Enter or = evaluates, Backspace deletes and Esc clears.
Is it private?
Completely. The calculator runs entirely in your browser using a built-in expression parser — there's no server and nothing you type is sent anywhere.
