How it works
- Choose how many digits and whether two or three numbers are added.
- Choose carrying in every sum, in none, or a mix.
- Choose how many sums go on the page, and keep the squares if the children line up digits badly.
- Download the PDF; the answers follow on the second page. Subtraction, multiplication and division are one click away.
Frequently asked questions
- What does “with regrouping” mean?
- A column adds up to 10 or more, so a 1 is carried to the next column. “None” picks only sums where no column reaches 10 — the first step — and “in every sum” makes every sum carry at least once.
- Why the squares?
- One digit to a square keeps the units under the units and the tens under the tens, which is where most column mistakes start. Turn them off for plain paper.
- Can I print a different sheet with the same settings?
- Change the sheet number. The sums come from that number and the settings, so the preview is exactly what you print.
- Is anything uploaded?
- No. The sheet is made in your browser. On the free plan a small line with our name is printed at the foot of the last page.
