Divisiblity Poset Diagram 2

I think there should be a line from the 30 to the 1 in the diagram "Divisibility poset {5,10,15,30}". Natschil (discuss • contribs) 07:37, 7 August 2013 (UTC)

problem sets?

Would it be possible to get problem sets along with each lesson? Diagrams are helpful but doing exercises help it sink in a bit better. --Farleyknight 04:47, 25 December 2008 (UTC)
