Using inverse operations
Recognise and use relationships between operations including inverse operations; use these relationships to check answers and simplify calculations
Typical age: 11–12 years
“If your child works out '252 ÷ 7 = 36', can they immediately use the inverse to check — '36 × 7 = 252' — without having to redo the division?”

Needs first
- Order of operationsREQUIRED
Understanding order of operations (BODMAS) is required before studying how operations undo each other via inverse relationships
- Multi-step problems: choosing operationsREQUIRED
Fluency with all four operations in context is required before formalising inverse relationships between them
