Turn a long equation into smaller cases by undoing its outside operations and bounding each bracket.
Read guideFind every solution without counting one twice
Use ordered cases, bounds and Mathoji’s duplicate rule to know when a puzzle is complete.
Read guideUse fractions as single puzzle choices
Read fraction keys correctly and work with exact values when whole-number arithmetic is not enough.
