How to use Naosu: grammar notes
•直す is an action you do to something, so always use the object marker を before it (e.g., 宿題を直す = fix the homework).
•You can use で to show where the fixing happens (e.g., 学校で直す = fix it at school).
•Don’t confuse 直す (to fix) with 直る (to get fixed); 直す is what you do, and 直る is what happens on its own.
