How do you like to take / store math notes?

Question

I always have difficulty with things like this but how do you like to take and store notes for later reference?

Paper and pencil? Physical books? Online notes? Where do you like to write them / upload them / store them?

Answer 1

I use an application called texstudio to write up my notes - so IOW, use LaTeX. It's a little bit difficult to begin with, but texstudio has very good facilities both to help with tex macros and for letting you compile easily as you work.

Answer 2

Pen and paper. The trick is that the writing reinforces the lecture, while typing doesn't. It is always useful to remember that multiple repetitions help reinforce what is being said.

Answer 3

Clearly and minimally

I must say don't agree with the rule that every answer needs to have 30 characters.
