Common mistakes
The misconceptions stored on this entity, with the correction to give.
Learners over-generalise a special case of the real number system to every situation.
Correction: Present a deliberate non-example and ask why the rule fails.
Students treat the real number system as a rule to memorise rather than a relationship to understand.
Correction: Anchor the rule in a visual model first, then abstract it — the model is the explanation.
