Wow. Jeffery, You are super with excellent explanation. If I guess that you are using mirror and both hands to write. !!!

I think you made a mistake here. You have n-i+1 variables in each row, not n-i. You need to include the column directly below the pivot

Why the "mutiliplication- addition" operation for zeroes below the pivots not counted???
