WebbYou could try John Lee's book Topological Manifolds, Ch 13 for singular homology (some definitions are in Ch 5). Then his book Smooth Manifolds, Chs 17 and 18 pick up where the previous book leaves off, and cover De Rham cohomology and its relation to singular homology. Obviously you'll need to be familiar with topology and smooth manifolds.

With cellular homology it is even easier since S n is the union of an n -cell and a 0 -cell. The chain complex has a single Z in degree 0 and a single Z in degree n. In all other degrees it is zero.
