Math worksheet generator
Endless practice sums with a matching answer key, and a number that brings the same sheet back.
It runs entirely in this browser tab: what you type is never uploaded, and the tool makes no network request while it works. Open your browser's network panel and try it — nothing leaves the page. There is no sign-up and no limit beyond what your own browser can hold.

How to use it
- Paste your text into the box above, or open a file.
- Adjust the settings beside it until the result is what you wanted.
- Copy the result, or save it as a file. The result updates as you type.
Questions
- Is what I type uploaded anywhere?
- No. This page carries the whole tool as WebAssembly and runs it on your own device. Nothing you type is sent anywhere.
- How exact is the arithmetic?
- Exact wherever an exact answer exists: fractions are rationals and money is decimal, neither goes through floating point. Where the answer is genuinely irrational — a root, a logarithm — it is computed digit by digit to the number of places you ask for, and the tool says whether it landed exactly or stopped there.
- Can I get this result again later?
- The settings travel in the page's address, after the #, so a link reproduces them exactly — and the fragment of an address is never sent to a server. Anything random takes a sheet number, so the same number brings the same worksheet back, answer key and all.
- Is there a version that is not a web page?
- Yes. The same tools are built as a desktop application from the same code, with a save dialog instead of a download and no network code at all.
