Reason - practice problems

In mathematics, reasoning is key to:

1. Problem solving – Helps analyze a task, choose the right procedure, and verify the result (e.g., "Does this answer make sense?").
2. Proving statements – Logical reasoning is needed when deriving formulas or geometric theorems (e.g., proving the Pythagorean theorem).
3. General generalization – Allows you to connect specific examples with general rules (e.g., "Why does the distributive law work?").
4. Critical thinking – Helps you detect errors in reasoning or calculations (e.g., "Is this step logical?").
5. Application of mathematics in practice – Allows you to select an appropriate mathematical model for real-world situations (e.g., calculating interest at a bank).

Without reasoning, mathematics would be just a mechanical repetition of procedures.
