"WebbUsing simplicial homology you can triangulate the sphere as the boundary of an ( n + 1) -simplex, and work out the chain complex by hand. 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.
