Free math calculators for every kind of problem
Choose a focused calculator or send any question to the universal solver. Every result is designed to show the reasoning, not only the answer.
Calculate it. Then understand it.
A focused calculator can check arithmetic and expose each step. The learning library explains why the formula works, when it applies, and how to recognize the same relationship in a new problem.

Open calculator →Common questions
Which calculator should I use for a word problem?
None of them on their own. A word problem has to be turned into an equation first, and that is the part a calculator cannot do for you. Read the question, name the unknown, write the relationship, and then pick the calculator that matches the relationship you wrote.
What is the difference between the calculators and the AI solver?
A calculator applies one method to values you supply, and it always applies that same method. The solver reads a problem in your own words, decides which method fits, and shows the reasoning. Use a calculator when you already know what to do, and the solver when you do not.
Are these calculators free?
Yes. Every calculator on this site is free to use with no account and no usage limit. An account is only needed for the AI tutor, because that runs a request against a language model.
Can a calculator show the steps, not just the answer?
Each calculator page carries a worked example with the arithmetic written out line by line, plus the conditions the method depends on. The calculator gives the value; the page beside it shows how that value was reached so you can reproduce it in an exam.
