hi James! I just wanna let you know how much your whole series of linear algebra has helped me out! Whenever I'm having difficulties understanding a term, I just watch your videos because your explanation is just great! I'm grateful for the time and efforts you put into making these videos and the fact that I'm watching these for free!

this slide depicts n and m being rows vs columns. Up to now, has this same notation meant the same eg, has R(superscript)n referred to rows vs R(superscript)m referred to columns or vice versa?
