Scientific Calculator
Evaluate advanced expressions with trig, logs, powers, roots, constants, history, and DEG/RAD modes
How to Use the Scientific Calculator
Enter expressions directly or use the keypad to build them without memorizing syntax.
1. Choose DEG or RAD
DEG treats trig inputs as degrees and inverse trig outputs as degrees. RAD uses radians for formulas from calculus and physics.
2. Build the expression
Use parentheses for grouping, ^ for powers, ! for factorials, log for base 10, and ln for natural logarithms.
3. Reuse recent work
History items can be clicked to load the expression again. The URL also updates so the current expression can be shared.

Scientific Calculator FAQ
Details about functions, angle mode, and expression syntax.
What functions does this scientific calculator support?
It supports arithmetic, parentheses, powers, square roots, factorials, base-10 logs, natural logs, trigonometry, inverse trigonometry, constants such as pi and e, and modulo operations.
Should I use degrees or radians?
Use degrees for most school geometry, angle measurements, and calculator-style trig examples. Use radians for calculus, physics formulas, and expressions already written in radians.
Why does log mean base 10 here?
Most handheld scientific calculators use log for base 10 and ln for the natural logarithm. This page follows that convention.
Can this solve algebra equations?
No. This is a numeric scientific calculator for evaluating expressions. It does not symbolically solve equations or simplify algebra.
How should I enter powers and factorials?
Use the ^ key for powers, such as 2^8, and use ! after a number or grouped expression for factorials, such as 5! or (3+2)!.
Is calculation history stored?
Recent calculations are stored locally in your browser so you can reuse them on the same device. They are not sent to a server.
