Scientific Calculator
Scientific Calculator evaluates complete expressions — type them or use the button grid — with parentheses, powers, square roots, trig functions in degrees or radians, logarithms, factorials, percentages, π, e and an Ans key for the previous result.
Last updated: July 2026
A scientific calculator evaluates full expressions with the standard order of operations — powers, roots, trigonometry (sin, cos, tan and inverses), logarithms, factorials, π and e. This one supports DEG and RAD angle modes, an Ans key for chaining calculations and a click-to-reuse history, and runs entirely in your browser.
How to use Scientific Calculator
- Type an expression or build it with the buttons.
- Pick DEG or RAD for trig functions.
- Press = (or Enter) and read the result; recent calculations stay in the history.
Frequently asked questions
What functions does it support?
Basic arithmetic, parentheses, powers (^), square roots, sin/cos/tan and their inverses, log (base 10), ln, exp, factorial (n!), percent, π, e and Ans.
How do degrees and radians work?
The DEG/RAD toggle sets how trig inputs and inverse-trig outputs are interpreted. DEG is the default, so sin(30) = 0.5.
Is my calculation sent anywhere?
No. Expressions are parsed and evaluated entirely in your browser — nothing is uploaded or stored.
