MISTAKE: Not being specific enough (e.g., saying 'many' instead of '5'). | CORRECTION: Use exact numbers whenever possible to clearly show the quantity.

MISTAKE: Mixing up units when showing quantities (e.g., saying '5 kg' for water when you mean '5 litres'). | CORRECTION: Make sure the unit you use (like kg, litre, meter) matches what you are measuring.
