Free Addition & Subtraction Worksheet Generator
Free printable maths worksheet generator — make endless addition and subtraction practice sheets. Set the number range, operations and problem count, then print with an optional answer key, at exact scale.
A worksheet generator gives you unlimited, fresh addition and subtraction practice — click “new problems” for a brand-new sheet every time, so a child never just memorises one page. Set the number range to match where they are (0–10 for beginners, 0–20, 0–100 and beyond as they grow), choose addition only, subtraction only, or a mixed set, and keep subtraction answers positive so early learners aren't thrown by negatives.
Pick how many problems fit the page and lay them out horizontally (a + b = ___) or in the classic vertical stacked column format with an answer line. Tick “answer key” to instantly print the same sheet with every answer filled in for quick marking. Everything is generated in your browser — print worksheet after worksheet at true A4 or Letter scale.
Printing at exact scale
Every sheet is drawn in real millimetres and prints at exact physical scale. For accurate output, set Scale = 100% (Actual size) and Margins = None in your browser's print dialog. Not sure your printer is honest? Run the printer ruler test first to confirm 50 mm really measures 50 mm.
Frequently asked questions
Does it make different problems each time?
Yes — press “new problems” for a fresh randomly generated set. Change the range, operations or count and it regenerates automatically.
Can I get an answer key?
Yes — tick “answer key” and the same worksheet prints with every answer filled in, so you can mark it in seconds. Print the blank version for the student and the key for yourself.
Can I avoid negative answers?
Yes — leave “no negative answers” on and subtraction problems are arranged so the answer is never below zero, which suits younger learners.
Horizontal or vertical layout?
Choose horizontal (a + b = ___) for quick mental maths, or the vertical stacked column format for practising written addition and subtraction with carrying and borrowing.
Is it really free?
Yes. Every template on printsheet.io is completely free, with no sign-up, no account and no watermark. Generate as many sheets as you like.
How do I get an exact-scale print?
Choose your paper size, then in the print dialog set Scale to 100% or “Actual size” and Margins to None. The sheet is defined in real millimetres, so it prints at true size. Use the calibration ruler page to verify.
Which paper sizes are supported?
A4, A5, A3, A6, US Letter, Legal and Tabloid, in portrait or landscape. Pick the size that matches the paper loaded in your printer.
Can I save it as a PDF instead of printing?
Yes — choose “Save as PDF” as the printer in your browser's print dialog. The PDF keeps the exact millimetre dimensions.
