omg Claire thank you -- you are sent from heaven. my lecturer never took the time to explain these variables and I understood right away with your content. your content here is on par with Sal Khan, the pace is great along with the clarity and presentation.
Thanks so much Michael! Since I've gotten two comments on this video now (a lot for me lol) I'll upload the PDF notes to go with this video in case they are helpful to anyone else! :)
My understanding is that the pivot should be a 1, which you can always get by dividing the row by whatever value is currently there. So, if you have something like 5 0 0 in your row, you can just divide by 5 to get it to 1 :) or if you are in the middle of the process and you have something like 2 4 8, you could divide by 2 to get the 1 in the pivot, so you'd have 1 2 4. I hope that helps!
@@mathematicaleconomist4943 yes it is! I did qualifying exams and graduate coursework in math, and then my dissertation was undergraduate math education focused.

Does the leading entry of the pivot beed to be 1? Or it could be any non zero number?
