Mental (Vedic) Subtraction Books 1 and 2 — interactive editions
One sutra — "all from 9 and the last from 10" — taken from 10 − 3 up to 10,000,000 − 517,559 and change from a £20 note. Every practice page of the printed book is typed on a keypad and marked as you go; seven worked sheets let the child reveal the sutra steps for any sum they are stuck on.

Questions
Before you join
What does the Family plan include?
Any 25 interactive books in full a month, for up to 3 children in one home, with progress and certificates saved for each child. New interactive books are added to the plan on release day. Printable PDFs are 20% off; the Family + Print plan adds 10 printable PDFs a month.
Can I cancel?
Yes, from your account in two taps. A monthly plan ends at the end of the month you've paid for; a yearly plan at the end of the year. Anything you downloaded on Family + Print is yours to keep.
Do I have to subscribe?
No. Every printable PDF is still sold one-off from $2.99, and the first chapter of each interactive book is free without an account.
What do I get when I buy a PDF?
A PDF you download straight after paying. It is also saved under My Materials so you can download it again.
Can I print it more than once?
Yes. The licence covers one family, or one teacher's own class. Schools and tutoring centres can ask about a site licence.
Which paper size?
A4. On US Letter choose "Fit to page" in your print settings.
Are the books AI-made?
Designed by Skillpedia. Some pages, such as worked examples and new puzzles, were made with AI tools and then checked by our team. Every answer key is verified.
Is the 11+ Mock Challenge a real 11+ test?
No. It is free practice under exam-style timing, written by Skillpedia and not connected to any grammar school, council or test company. It covers the skills most 11+ tests use, but every area sets its own test and pass mark, so the score is a raw mark out of 60, not a prediction.
Is the Puzzle Challenge free?
Yes. Every child aged 6 to 12 in the UK can enter once per half-term challenge, entered by a parent or guardian, with no purchase needed. Answers are marked straight away and every finisher gets a certificate. The full rules are on the challenge page.
Refunds?
Digital files can't be returned, but if a file is faulty we replace it or refund you.
