Mathematics and general calculation tools
Last updated August 27, 2026
This Math Solver solves algebra, trigonometry, and calculus problems and shows the full working, not just the final answer. Type an equation or expression the way you'd write it by hand - "x + y = 7, x + 2y = 11" for a system of equations, "x² - 5x - 12 = 0" for a quadratic, "d/dx x³" for a derivative - and it identifies what kind of problem it is, solves it, and narrates each step in plain English.
It's built on the same calculation engines that power this site's dedicated Algebra, Fractions, and Numbers & Arithmetic calculators, so a solved equation here is exact, not an approximation - the same arithmetic runs either way, this page just adds free-text input and automatic problem detection on top.
Example problems
What This Math Solver Can Do
Algebra
Linear equations (ax + b = c), quadratic equations (ax² + bx + c = 0) with real, repeated, or complex roots, 2x2 systems of equations solved with Cramer's Rule, and basic fraction arithmetic and simplification.
Trigonometry
Numeric evaluation of sin, cos, and tan at any angle, inverse trig (arcsin, arccos, arctan), and common-angle trig equations - each result explained in terms of the unit circle or a standard identity, not just returned as a number.
Calculus
Derivatives and indefinite integrals of polynomial expressions in x using the power rule, plus a small set of classic textbook limits (like lim x→0 sin(x)/x). Chain rule, product rule, and trig/exponential/log calculus aren't supported yet.
FAQ
What can this Math Solver do?
It solves algebra (linear equations, quadratic equations, systems of two equations, and fractions), evaluates and solves trigonometry problems, and computes calculus derivatives, integrals, and a set of classic limits - all from free-text input, with full step-by-step working shown for every result.
Is the Math Solver free to use?
Yes. There's no sign-up, no usage limit, and no paywalled step-by-step - every solution, including the full worked steps, is free on every problem type this tool supports.
Does it show step-by-step solutions, or just the final answer?
Every solved problem includes the full step-by-step working - which formula or rule was applied, each intermediate calculation, and how the final answer was reached - not just the result on its own.
Can it solve a system of two equations?
Yes - enter both equations on one line separated by a comma (e.g. "x + y = 7, x + 2y = 11") or on separate lines, and it solves for x and y using Cramer's Rule, showing the determinant and both intermediate determinants (Dₓ and Dᵧ) along the way.
Can it solve quadratic equations with no real solution?
Yes. When the discriminant is negative, the solver correctly reports the two complex conjugate roots (in a + bi form) instead of failing or forcing a real-number answer that doesn't exist.
What trigonometry problems can it handle?
Numeric evaluation of sin, cos, and tan for any angle, the inverse trig functions (arcsin, arccos, arctan), and equations built around the common unit-circle angles (0°, 30°, 45°, 60°, 90°, and their standard multiples).
Can it find derivatives and integrals?
Yes, for polynomial expressions in x: type "d/dx x³ + 2x" for a derivative or "∫ x² dx" for an indefinite integral, and it applies the power rule to every term and shows each one worked out, including the constant of integration.
What kinds of problems aren't supported yet?
Chain rule, product rule, and quotient rule calculus; trig, exponential, and logarithmic derivatives/integrals; general (non-textbook) limits; equations with more than one variable outside a 2x2 system; and multi-step algebraic simplification beyond a single equation. The solver says so honestly rather than guessing when a problem falls outside these bounds.
How is this different from the individual calculators listed below?
The calculators below each handle one problem type through a structured form (enter a, b, c for a quadratic, for example). This solver reads a plain-text problem, works out which of those calculators applies, and runs it automatically - useful when you'd rather type the equation as written than pick the matching calculator yourself.
Do I need to create an account or install anything?
No. The Math Solver runs entirely in your browser once the page loads - no account, no installation, and no data leaves your device to solve a problem.
