I'm sorry to hear that you've been experiencing frustration through your educational experience. I'm sure that that frustration is on both ends of teaching through the pandemic. I'm glad you found benefit from this example.
@@davidfriday7498 things were same before the pandemic too these college professors have absolute power and it has corrupted them absolutely, most of the time they genuinely don't give two shits about making the lecture engaging or easy to digest
@@hamzamaken9323 your experience is far too common. I know plenty of people in my profession that are simply in it for the paycheck rather than in it for the experience. Please know that there are plenty of us out there that are doing our best for our students. Find those professors and get to know them. Outside of the classroom, we are people, just like you.
why did you pull the 8 out? when you can simply just divide by 8? since this is a matrix? why was the 8 outside on the side? I thought you can simply just divide it by 8 and that would still be the same matrix ]
The short answer is "no, it would not be the same matrix." Dividing something by 8 changes its value eightfold; literally the definition of division. I believe you are thinking about operations that can be done to both sides of an equation. If you divide both sides of an equation by 8, then yes, the equation is equivalent to its predecessor. But arbitrarily dividing something, like an expression, a matrix, or a row of a matrix, by 8 does indeed change its value.
@@davidfriday7498 how about row reduce echelon form? i was taught that i can switch rows and take division and multiplication to cancel out also would another way to do this , getting it down to row reduce echelon form and doing a multiplication of lamda cross multiplication? Thank you
Thanks you, sick of worthless teachers and textbooks, they make these classes an absolute waste of time.

You titled your video as elementary row operations but never used a row operation, instead used only column operations...
A title can only have 100 characters. Changing "row" to "column" puts me at 101 characters. So... pretend I used a transpose?
