@Chris'ssis Could you do me a favor and view that thread and tell me the upvote and downvote counts? I only ask because I believe you have sufficient reputation
@hjhjhj57 That would be my second preference, but I feel as though people will put up my answer pretty much and be wasting the time of valuable helpers who could be helping others - I also think I will get a faster reaction for doing it this way
In that case I would agree with you, but in the case of that question, I have never seen an answer to such a problem, but felt that it was only one that would work
@hjhjhj57 I want to be able to discern if my question or my answer are the upvoted thing and if I get upvoted I know it is the right answer, and if it is downvoted I will delete
@hjhjhj57 It says that it is acceptable to post your own answers in the help page, and also are you saying I am getting free rep for posting my own answers? I have done this 5 times and I have 21 rep...
@MhenniBenghorbal Thank you, does that include my attempt at the notation? Or should it be a list like in the book? $\operatorname{Basis } U = ((3,1,0,0,0),(0,0,7,1,0),(0,0,0,0,1))$ instead of a set?
