Stack the numbers and crunch them one column at a time — ones, tens, hundreds — carrying and borrowing across the line to build each answer digit.
Numbers are stacked and solved column by column — ones first, then tens, then hundreds — with carrying and borrowing happening wherever the arithmetic requires it. This reinforces column addition and subtraction, regrouping, and the place-value understanding that makes each digit's position meaningful. Suited to Grades 2–4, or any child working through the standard written algorithms for the first time.
A free, no-signup, no-ads math game for Grades 2–4 — practising addition, subtraction, regrouping, place-value. Play in your browser on the KidsDoMath games hub or explore more Arithmetic games.
