Online scientific calculator

Your files never leave your computer: everything runs in your browser.

Type fractions, roots and integrals as on paper and get exact results like ½, √2 or π/3. Twelve modes: complex numbers, matrices, statistics, equations, distributions and more.

How to use it

Use the on-screen keys or type with your keyboard: cos(60), sqrt(8), int(x^2,0,1)…
MENU switches mode; OPTN opens the mode's functions; SHIFT MENU opens the setup (degrees/radians, decimals…).
Press = (or Enter). S⇔D toggles between exact and decimal results.
