I mean "the way you remember"

Pay attention to the question and you will get it. It is asking about REMEMBER not about "to buy" or "buying".

remember to do: remember something and then do it remember doing: something happened in the past and now you remember it. remember is one of those verbs which can be followed by another verb in either the infinitive or 'ing' form. The meaning changes. I remebered to shut the gate. First I remebered to do something then I did it. I remember closing the gate I did it and now I recall doing it.

" I’m trying to learn Japanese but it’s very difficult." " I'll try to get there as soon as I can. (An effort is implied)" Try + to + infinitive means that something is difficult and you make an attempt to do it. -How can I remove the stain from this T-shirt? It won't go!!!! -Try using that new soap powder you saw on TV. " Have you tried using butter instead of oil?" Try + ‘ing’ means make an experiment. It’s not difficult – it might work, it might not.

No, is't not. As you well said before, you can't double negate in English. "Don't stop, never give up"... I think that there is a song called "Don't stop, never give up" by S Club 7. Hhahaha. I hope it helps.

If I were you = Si yo fuera tú/usted. It means what I would do if I were in someone else's place. Si yo fuera tú, viviría lejos de aquí = If I were you, I would live away from here.
