Long multiplication and division, shown step by step.
Altus Maths works each sum the column way — the same method taught in school — writing every carry and every stage as it goes. Children watch it done, then practise themselves, with printable worksheets and progress that follows them from one device to the next.
Runs in any modern browser — nothing to install. Works on a phone, tablet or computer.
What children can do
Four ways to build confidence with bigger sums — watch, practise, print and track.
See it worked out
Each stage appears in order, with the current column highlighted and every carry written in — exactly as it's taught.
Practise at their level
Multiplication or division, with levels that grow. Questions are marked instantly, right or wrong, with the time taken.
Print worksheets
Generate a tidy A4 worksheet to do on paper, with an answer sheet — handy for homework or a quiet ten minutes.
Save their progress
Sign in with just a nickname to keep a record of every question. Sign in on another device and the results are there too.
The methods it teaches
The same written methods used in primary and lower-secondary classrooms — not shortcuts.
Long multiplication
Multiplying by each digit in turn, carrying between columns, then adding the partial answers together.
Short & long division
Dividing column by column, carrying the remainder across, and setting the answer out above the line.
Reading the carries
Small carried figures are shown where a child would write them, so the paper method and the screen match.
Made for…
Children at home
Practise the exact method from school at their own pace, with instant feedback.
Parents

Private by design
- Unlisted. Nothing links here and the pages ask search engines to skip them — it's for people you share the address with.
- Only a nickname and a password are kept for an account, and the password is stored hashed (bcrypt), never in plain text.
- Just the results — the questions, answers and times — are saved, so progress can follow a child between devices.
- Delete anytime. A signed-in child can remove their account and every result with one button.
