I am a bit puzzled by the following. You know how they teach you that in order to find column space you just need to row reduce the matrix, look at the columns with leading 1's in them and then just read off those columns from the original matrix? Well, why does that actually work? I'm trying to get my head around this, but so far I don't think I've quite gotten there. So if there's anyone that could expand this or link me to some online explanations, that would be greatly appreciated.
