Scientific Calculator

Our Scientific Calculator gives you the precision and flexibility of a handheld scientific calculator—right in your browser. Switch between degrees and radians, perform trigonometric and inverse trigonometric functions, calculate powers, roots, factorials, percent/modulo, and natural/decimal logarithms. It also includes memory keys (MC, MR, M+, M−), a result history, and keyboard input for fast calculations.

Key features

Basic ops: + − × ÷ with parentheses and precedence
Trig & inverse trig: sin, cos, tan, asin, acos, atan (DEG/RAD)
Exponents & roots: xʸ, √, ∛, x^(1/n)
Logs: ln, log10, exp, constants π, e
Extras: x², 1/x, abs, n!, % (modulo), ANS recall
Memory: MC, MR, M+, M−
History list with one-tap reuse
Keyboard support & responsive layout

Note: % is treated as modulo (remainder). If you want percent-of (e.g., 15% of 200), enter 200 * 15 / 100.

Mode: DEG · ANS = 0

History

Supported: + − × ÷ ^ ( ) , sin cos tan asin acos atan ln log exp abs √ ∛ x² 1/x n! π e ANS, and modulo %.
