I am taking an introductory Algebraic Topology course, and we have just finished talking about the fundamental group/ covering spaces in Munkres' Topology. However, his treatment of simplicial homology in Elements of Algebraic Topology has been particularly opaque to me.
I'm wondering specifically about a text that focuses on Simplicial homology theory [that doesn't assume a lot of requisite algebra], as well as a clear/geometric consideration of what a simplicial complex is in the first place. Some particular problems I'm having include the following:
Abstract Simplicial Complexes
Linear homomorphism/ geometric realizations
[somewhat an aside] free abelian groups/ direct sums/summans and their use in computing homology.
I'm looking for something that doesn't assume too much, but also motivates the definitions, since this is my first time dealing with homology, and I've yet to see how any of this comes together.
