My personal take: learning and making proofs is important because you get to understand the point of the more abstract topics (such as vector subspaces, orthogonal complements, direct sums, etc.)
And then you have new tools for thinking.
- dragandj 9y agoYes, and the reader should do that following the textbook. There was nothing special that I could add to that.
- thanatropism 9y agoYes, but the tutorial isn't suggesting the reader go do proofs. Instead he says these more advanced topics are unnecessary. I said: their necessity is not apparent until you try doing proofs; but then you see them everywhere like a man with a hammer sees nails. Mind, his approach may well be the correct one for the context, but you're saying he's doing things my way, which he's not.
