What a good step-by-step solution includes

  • 01

    One move per line

    Every numbered step makes a single change, such as expanding a bracket or subtracting from both sides, and shows the result.

  • 02

    The reason, not just the move

    In Detailed teaching each step names the rule it uses, so you can apply the same move to the next problem on your sheet.

  • 03

    A check you can read

    Before the answer, the result goes back into the original problem with the numbers written out, so a slip is easy to spot.

  • 04

    Honest about odd problems

    If a problem can be read two ways, has no solution or lacks information, the solution says so and shows why instead of forcing an answer.

How to get a solution with steps

  1. 01

    Type it exactly

    Copy the problem as written, including the instruction: solve, simplify, factor, prove or find.

  2. 02

    Choose the level

    Answer + steps to check homework; Detailed teaching when you are learning the method for the first time.

  3. 03

    Compare with your working

    Find the first line where your working differs. That is usually the mistake worth fixing.

A worked example, step by step

This is the layout of an Answer + steps solution, worked by hand for this page so you can see what to expect. Your own solution is written by the model and follows the same layout.

  • Problem: Solve 2x^2 - 5x - 3 = 0
  • 1. Find two numbers with product 2 × (-3) = -6 and sum -5: they are -6 and 1
  • 2. Split the middle term: 2x^2 - 6x + x - 3 = 0
  • 3. Group: 2x(x - 3) + 1(x - 3) = 0, so (2x + 1)(x - 3) = 0
  • 4. Set each factor to zero: x = 3 or x = -1/2
  • Check: 2(3)^2 - 5(3) - 3 = 18 - 15 - 3 = 0, and 2(1/4) - 5(-1/2) - 3 = 1/2 + 5/2 - 3 = 0
  • Answer: x = 3 or x = -1/2

Answer + steps or Detailed teaching?

Answer + steps keeps each line short and the whole solution to about one screen. It suits checking homework or a quick reminder of a method you already know.

Detailed teaching opens with the idea, for example 'a product is zero only when one of its factors is zero', gives a reason after each step, names a mistake students often make and ends with a practice problem and its answer. Both levels cost the same.

Why the check line matters

Language models write fluent working, and fluent working can still hide a sign error. The check line puts the answer back into the original problem with the numbers written out. If the check fails, the solver is told to find and fix the mistake before it gives the answer. Read the check anyway: it takes ten seconds and is the quickest way to trust a result.

A free math problem solver? What is free here

The account, the worked examples, the formula list and the test problems on this site are free. Solving your own problems uses purchased credits from the first problem: there is no free daily quota and no signup bonus. Packs start at $4.99 for 50 problems, and credits do not expire while your account is open.

Step-by-step solver FAQ

Is this a free math problem solver?

The account and the worked examples on this site are free, but solving your own problems uses purchased credits: 1 credit per problem, $0.08 to $0.10. There is no free daily quota or signup bonus. Packs start at $4.99.

How many steps will I get?

As many as the problem needs, one operation per line. A one-step equation takes two or three lines; a quadratic or a word problem with several parts takes more. Detailed teaching adds reasons, not extra arithmetic.

Can I ask a follow-up question?

Each solution is a single answer, not a chat. To go deeper, solve again with Detailed teaching, or type a new problem that asks about the step you want explained; each new solution uses 1 credit.

Will the steps match my teacher's method?

Often, but not always. The solver uses standard methods and names them, such as factoring or the quadratic formula. If your class needs a particular method, say so in the problem, for example 'solve by completing the square'.
