1/ An abelian category is one which has all the nice properties of abelian groups.
So every map comes with a kernel, a cokernel and an image, which fit together in a nice way:

In #mathstoday my further math class split three ways: year 13 looking at conservation of energy, some of them started on #Ritangle problem no 1, and year 12 trying to invert 3 x 3 matrices, the poor sods.
