Use the full chart tool. Click a value to zoom in and explore the fraction row. The equation reveal is hidden, but you can still use the groups view and select a fractional part.
Mild
The chart can only highlight rows. You can hover to inspect a value on the times table chart, but you cannot zoom into the fraction tool.
Medium
Static chart only. No row highlight and no zoom tool. Use the chart as a plain reference.
Spicy
No chart at all. Questions come from a hidden 13 to 20 times table range, while still keeping whole-number answers.
