Not there yet.

Answer 7

Thanks anyway

Answer 8

Don't we need to establish the set of elements in the group?

Answer 9

I don't know. I think we need the group, right?

Answer 10

I never took this course. I know what a group is, but I don't know any important theorems used to prove them, so I could only prove them by their definition.

Answer 11

whatever, please tell me something. I am behind the course
