The person teaching you may need to see your attempt before knowing what to explain.

Asking to have it explained again often produces the same explanation again. A teacher cannot see where your understanding breaks from the outside; they can only see the general shape of the topic, so they repeat the general shape. An attempt, even a bad one, shows exactly which step went sideways, which turns a vague lesson into a specific correction. Waiting until you understand before trying keeps the useful information hidden.

Try the thing badly and bring the mess to whoever is teaching you. Say where you got stuck rather than saying you do not understand. Most teachers get far more helpful the moment they can see your working.
