# About Math Solver Calculator

Math Solver Calculator is an independent web app that solves typed math problems with step-by-step working and a written check. We run the model for you, show the price before every problem, and refund failed solutions automatically.

## What we do

Students, parents and anyone returning to math tend to get stuck on the same thing: an answer without the steps. Math Solver Calculator writes the steps, one operation per line, checks the result and ends with a clear answer in plain text you can copy.

## The model and the rules

Solutions are written by Claude Sonnet 5 through a commercial model API, guided by our own solving rules: one step per line, exact values until the end, units kept, a written check before the answer, a note when a problem is ambiguous, and plain-text notation without LaTeX. Requests that are not math are refused, and their credit is refunded.

## What we do not promise

AI models can make mistakes, and the check line reduces them but does not remove them. We do not claim an accuracy rate. Verify answers that matter, and follow your school's rules on outside help. The site reads typed text only: there is no photo upload and there are no graphs at the moment.

## Pricing you can check

Every problem costs 1 credit ($0.08 to $0.10), shown before you solve. Registration is free and includes no credits. Packs start at $4.99 and plans at $7.99 a month; failed solutions are refunded automatically.

## Your problems

Problems and solutions are stored so you can see your history, and are sent to the model provider only to produce your solution. We do not sell them or use them to train models. You can ask us to delete your account and its history from the email address on your account.
