Important question patterns for Number Systems

Understand rational and irrational numbers and their decimal expansions. The best question practice covers Irrational numbers, Real numbers and Representation, but it also checks whether the student can choose the method independently. Eduro can generate fresh variations so practice does not become memorisation.

Irrational numbers
Real numbers
Representation

Must-practice concept questions

These questions check whether the student understands the basic idea before moving to exam-level complexity.

Explain Irrational numbers in your own words.
Give an example where Real numbers is used.
Compare two related ideas from Irrational numbers, Real numbers and Representation.

Application questions

Application questions hide the concept inside a situation. Students should practise identifying the idea before solving.

One easy question from Number Systems.
One mixed question where the method is not obvious.
One question that asks for reasoning, not only the final answer.

Mistake-analysis questions

A mistake-analysis question trains the student to recognise wrong reasoning. This is one of the fastest ways to improve marks.

Find the first wrong step.
Explain why it is wrong.
Rewrite the corrected solution cleanly.

How to use this page well

Important questions work only when followed by review. Eduro should turn every wrong answer into a smaller concept repair session.
