Linear Algebra Lecture 3: Subspaces and proofs of elementary properties

[Anonymous-cwyd]

First of all, thank you so(×2) much for uploading this lectures course on linear algebra. Time stamp: 37:20. I would prove uniqueness of additive identity in the following way: let 0 and 0' be additive identity of V. By definition of additive identity, 0=0+0'=0'. Thus 0=0'.
