What it costs
Nothing yet, and here is what it will cost when it does. 65 worked
examples are free to anybody — two from every pattern, each with its practice
questions — so you can meet all 33 without a code and without paying.
Open, in full, while it is being tested
MathBrush is being shown to a few parent groups before it opens properly, and for them
every solution, every practice question and the whole worksheet builder is open. If you
came from one of those posts, the code is in it.

Questions people ask first
- Why will it cost anything?
- Every solution here is drawn, solved again independently, and checked before it is
published, and new ones are made every week. The subscription is what pays for that
work.
- How long is the beta?
- A few weeks per group, while I find out what is confusing and fix it. Nothing you use
now stops working when it ends: the free examples stay free, and you will not be
charged for anything without being asked first.
- Can I cancel?
- Any time, from the link in your receipt. A year bought is a year kept.
- Is it per child?
- No. One subscription, one household, however many children are using it.
- How do I pay?
- PayNow or a card.
- What if a solution is wrong?
- Tell me and I will fix it — shawn@mathbrush.sg.
