Proof of the Mayer Vietoris Sequence

In this video, I will prove the Mayer-Vietoris sequence and it's more general form. This will assume knowledge of homology, algebraic topology, and chain complexes.

why and how the fuck do you know such high level advanced math

Trivial correction @ 10:00, I think Idempotent operators are operators where applying them twice is the same as applying them once (i.e. ∂∘∂ = ∂). E.g. Projections would be an Idempotent operator but boundary maps wouldn't be I believe since ∂∘∂ = 0 for chain complexes.
