## Tools

- [Math Solver](https://mathsolverfree.xyz/): Type an equation or expression, see every step of the solution.
- [Examples](https://mathsolverfree.xyz/examples/): Worked examples: linear equations, quadratic equations, and arithmetic, step by step.
- [Order of Operations](https://mathsolverfree.xyz/order-of-operations/): A reference for PEMDAS/BODMAS, the rule the solver's arithmetic steps follow.

## Key facts

- Solves plain arithmetic with full order of operations (parentheses,
  exponents, multiplication/division, addition/subtraction), linear
  equations in one variable, and quadratic equations in one variable
  (including no-real-solution and repeated-root cases).
- Uses mathjs (an actively maintained, open-source math library) for
  expression parsing, safe evaluation, and polynomial expansion; the
  equation-classification and step-narration logic on top of it is original.
- Reports plainly when an equation is a contradiction (no solution), an
  identity (true for every value), or outside current scope (degree 3+,
  more than one variable, or a non-polynomial equation) instead of
  guessing at a wrong answer.
- No account, no server upload, no tracking cookies. All solving runs
  client-side.
