MathBrush is being tested with a few parent groups, and every solution on the site is open to them — one household, all children. If you were given a code, it goes in once and this device remembers it.

65 worked examples are free without a code, two from every pattern. No account, either way.
One batch repeats. Work out one batch, then multiply.
Items are described as a fixed group or ratio that repeats, such as tiles following a pattern, snacks sold in a fixed mix, or a rate given per hour or per item.
Children start from the grand total instead of first working out what one batch is worth. In rate questions they also confuse a duration with a clock time.
