Every Clear Math tool can live on your own pages. Pick a tool, copy one snippet, and your readers get the full working calculator — free, always up to date, and no attribution required.
1 · Pick a calculator
2 · See it live
3 · Copy the snippet
Paste this where you want the calculator to appear. The height is set to 640px — adjust it to fit your layout; the calculator is fully responsive inside the frame.
Why embed ours?
Your readers get the answer and the explanation together: a student checking a grade mid-homework, a parent splitting a tip fairly, a shopper comparing unit prices. The calculator is the same one we run here — every mode, every step shown — not a cut-down widget.
Built for teachers, school and homework sites, parenting blogs and community resource pages. When we improve a calculator, every embedded copy improves with it — you never have to touch your pages again.
The terms — short version
Free for any site — personal or commercial, as many calculators and pages as you like.
No attribution required — the widget carries a small “Calculator via Clear Math” line on its own; you add nothing.
Use it as-is — please don’t modify the calculator, disguise it as your own product, or remove the built-in “via” line.
Estimates only — results are estimates, not financial, tax or legal advice; that note travels with the widget.
Frequently asked questions
Is it really free?
Yes — free for any website, including commercial sites. There is no paid tier, no watermark and no usage cap.
Do I need to credit Clear Math?
No. Attribution is not required. The widget carries one small “Calculator via Clear Math” line of its own so your readers can find the full library — you do not need to add any link or credit yourself.
Will it slow my site down?
The widget loads on demand inside an iframe and runs entirely in the reader’s browser — no libraries, no trackers, nothing added to your own page weight beyond the iframe itself.
Can I change how it looks or how it calculates?
Please use it as-is: do not modify the calculator, restyle it to look like your own product, or remove the small “via” line. You can set the width (100%, 720px or 480px) and adjust the snippet’s height to fit your layout.
