Scientific Calculator
Tap keys, type directly, or use your keyboard. The keypad inserts into the field you are currently using.
Calculus
Use these when you need numerical calculus. The keypad still works in any field that has focus.
Scientific mode
Use the calculator display above for expression entry. Supported functions include sin, cos, tan, asin, acos, atan, sqrt, ln, log, exp, fact, abs, Ans, and memory M.
Derivative at a point
Definite integral
Algebra
Solve common algebra problems with steps and clean results. This is the part most people expect from a Mathway-style page.
Linear equation
Solve ax + b = c.
Quadratic equation
Solve ax² + bx + c = 0.
2x2 system
Solve two linear equations in two unknowns.
Graph and Solve
Plot one or two functions, inspect their shape, and numerically find x values where the expression equals zero or where two graphs intersect.
Graph f(x)
The graph will appear here after you plot a function.
Equation solver
Examples
This tool uses numerical calculus, not full symbolic algebra. It is intended for quick checks, not proof-level derivations.
How It Works
Scientific mode
Evaluates expressions with trig functions, powers, roots, logs, constants, and parentheses.
Derivative mode
f'(x) \u2248 [f(x+h) - f(x-h)] ÷ 2h
Integral mode
\u222B f(x)dx \u2248 Simpson's rule over the requested interval.
Trig support
Choose degrees or radians. Forward trig uses the selected angle unit; inverse trig returns angles in the same unit.

Math Solver FAQ
Does it handle trig?
Yes. Degrees and radians are supported, along with inverse trig.
Can I use a keypad?
Yes. The page has a calculator-style keypad with memory and quick insert buttons.
Can I find roots?
Yes. The equation solver searches an interval and returns roots numerically.
Is graphing interactive?
Yes. You can plot one or two functions, inspect a table, and search for intersections.
