How to use Algebra Calculator
Simplify, expand and factor expressions, solve equations and small systems, take derivatives and integrals, or evaluate a formula with values. Results appear as formatted math with a plain-text copy, and quadratic equations come with the solving steps.
- 1
Choose an Operation: Simplify, Expand, Factor, Solve, Derivative, Integral or Evaluate.
- 2
Type the expression or equation, using ^ for powers (for example x^2-5x+6=0), or pick one from Examples; separate the equations of a system with ; or new lines.
- 3
Optional: set the Variable, the derivative Order (f′, f″, f‴), the Definite integral bounds, or the Values such as a = 3, b = 4.

Frequently asked questions
Does it show step-by-step working?
Only for quadratic equations, where it shows the coefficients, the discriminant and the quadratic formula. Other operations show the final result.
Can it solve systems of equations?
Yes. Type the equations separated by ; or on separate lines, for example x+y=3; x-y=1. When no exact form is found, it lists numerical solutions.
What happens when an integral has no closed form?
For an indefinite integral it tells you no closed-form antiderivative was found. If you enter bounds, it still computes the definite integral numerically with Simpson's rule.
How should I write expressions?
Use ^ for powers, * or juxtaposition for multiplication (2x), and sqrt, sin, cos, tan, ln (natural log), log10, abs, e and pi.
Can I trust the simplified result?
Where possible the result is checked numerically at random points, and the tool says so under the result. It is still worth a quick look for domain issues, such as a factor that was cancelled.
