On Friday I spoke about equivalence relations and residue classes mod an integer.

I have posted the missing page 32.

I have posted some old notes of mine.

Firstly, a note about sets, which you might find useful. We will be using sets and maps all the time.

Secondly, a note about the symmetries of a square, one english and one norwegian version which is meant as a motivation for the introduction of groups. I'll talk about that to day.
