Let $X$ be the 2 complex obtained from $S^1$ with its usual cell structure by attaching two 2 cells by maps of degrees 2 and 3 , respectively. (a) Compute the homology groups of all the subcomplexes $A\subset X$ and the corresponding quotient complexes $X/A$.
I'm having trouble with this problem, the subcomplexes should just be the skeleta right? I'm very confused could anyone get me started here?
