What is a math crossword?

A math crossword (also called a cross-number puzzle) is a crossword-style grid where each entry is a number. Instead of word clues, each Across and Down clue is an equation — solve it and write the answer digit-by-digit into the boxes.

What operations are used?

Easy uses addition and subtraction. Medium adds multiplication. Hard uses all four operations including division — perfect for full arithmetic practice.

What grid sizes can I choose?

3×3 for younger learners, 4×4 for general practice, and 5×5 for advanced solvers. Larger grids mean more clues per puzzle.

Yes — every puzzle is generated from a fixed digit grid, so each clue has exactly one correct answer and every cell has one digit.

Can I make a full math crossword book?

Yes — generate up to 50 pages at once and download a single print-ready PDF with a matching answer key.

Does it work on mobile, iPad, and Chromebook?

Yes. The math crossword maker runs in your browser — no app required.

Do you store my puzzles?

No. Everything is generated in your browser session. We don't store, sell, or share your data.

Is this worksheet maker really free to use?

Yes — start without a credit card. Manual mode is always free to use and does not spend AI word credits. On the free plan you get 5,000 lifetime AI words (one trial per network), up to 10 PDF downloads per day, and a subtle eduzuma.com watermark on exports. Basic, Pro, and School plans remove the watermark, lift daily limits, and include a commercial resale license.

Do my PDF downloads have a watermark?

Free-plan and guest PDFs include a small eduzuma.com footer watermark. Paid plans (Basic, Pro, School) deliver 100% watermark-free PDFs — the upgrade most teachers and KDP publishers choose.

Is there a daily download limit?

Free and guest users can download up to 10 PDFs per day (tracked in the app). Paid plans include unlimited daily downloads.

Can I sell worksheets or puzzle books commercially?

Classroom and personal use are included on the free plan. Selling on Teachers Pay Teachers, Amazon KDP, Etsy, or similar requires Basic, Pro, or School — each includes a royalty-free commercial license and watermark-free PDFs.

Can I download multi-page worksheet packs on the free plan?

The free plan exports one page per generation. Basic supports up to 5 pages per click; Pro and School support unlimited multi-page packs — ideal for workbook sets, puzzle books, and full classroom packets.
