It took me 5 days to fully understand Gauss-Jordan Elimination. I have now, after many attempts, come to a conclusion that you ALWAYS have to do this when you start (the example is a 3x4 but the rule is for all): - - | 1 x x | x | | x x x | x | | x x x | x | - - - - | 1 x x | x | | 0 x x | x | | x x x | x | - - - - | 1 x x | x | | 0 x x | x | | 0 x x | x | - - After you have done these three steps you need to check if there’s a “1” in the middle of row two or three. If there’s no “1” in the middle of row two but there’s a “1” in row three, you need to swap row two with row three. If there’s no “1” in either, you have to find the pivot in row two and turn it into a “1”. These steps are the fundamental of Gauss-Jordan Elimination. The other steps will become clear after these steps.

Solving by both ADDing and SUBTRACTing rows instead of just always ADDing them may make some people prone to more errors when solving... You may have said it in the video, since I skimmed through, but for anyone who doesn't see it, when you ADD rows like ( R1 + R2 ) ONLY row R2 will CHANGE. And when you SUBTRACT rows like ( R1 - R2 ) ONLY R1 will CHANGE. My professor explained it to us as if there's no such thing as subtraction.. Since you can say... R1 + (-R2) = R1 - R2 I Always ADD rows and Never subtract so I can try and make it easier on myself to remember that only the right side of the addition problem will be the row that will be changed. For me, this is easier when I'm in a rush not to make mistakes. Because doing it your way just adds another step to think about and is something you need to consciously be aware of so you don't switch the wrong row. As an example at 5:40min in the video instead of your way.... 3(R1) - R2 {Where only Row 1 changes} I would do... -3(R1)+R2 {Where only Row 2 changes} I always ADD the rows and never subtract and just know the right side of the addition problem is the row that will be changed. This is just something that helped me make fewer mistakes and possibly save a few seconds time. Its good to get as many perspectives as you can though to find out which way is better for each individual.
you can simply assign the value of the operation to a row for example R1-R2 ---> R1 and this would be less likely to cause you errors while still substracting

Im not following whats going on at 1:53. Your notation in the top right says you are going to be taking away R2 from R1 ( R1-R2 ) surely that should be the other way around ( R2 - R1 ). This also makes it so that its -1 - 1 = -2 which would have further implications on the rest of the calculation.

In the first part , you've calculated R1-R2 ( 01:50 ) and R1 has stayed untouched only R2 has changed , but later you've done 3R1 -R2 and the R1 has changed not R2. So when you're transforming the elements under the first diagonal , R1-R2 means that R2 is changing , and when you're above the diagonal , R1 is changing?

No because when you try to get your zeros you mess up the main diagonal 1's the nice thing about having zeros first is that it's hard to accidentally get rid of because anything multipled by zero stays zeros

Bro I can't thank you enough! I'm literally in shock I just get it and I can't believe ittt.. my prof discuss this and I can't even understand anything he said you deserve my tuition broo!!!
I’m confused with the order of operations, I thought it went from a1,1 being the first step diagonally down and then a2,2 being the 4th step. Ile keep watching but I’m hoping Ile understand this.
Probably too late an answer but others might wonder: Order of operations is irrelevant. Get a 1 in the upper left corner, do operations until the rest of the numbers in the columns are 0. Then repeat until you get a 1 in the entire diagonal, rest of the matrix zero.
For everyone (if any of you are gonna see this), I was confused as well, he, for some reason, when makes the R1 - R2 or any other Rx - Ry, he modifies the right row (Ry). R1 - R2 he ends up doing R2 - R1 (as most of us see it) and of course the line end up being negative. The thing is, it doesn't matter, you can multiply any constant anytime, in this case, I am talking about -1, depends on the case u are in.

I've noticed some issues with actually doing the problems, so let me share what I've learned: In order to solve these, you need to generate zeros. In order to generate zeros, you need to generate ones, but that isn't too hard. Generating ones is easy, since all you need is an even and an odd number in the same column. If this doesn't work, you can also try dividing a row by a common multiple (E.X: 3 6 6 -> 1 2 2). When you have a one in a column, what you want to do is move that row to the top, then make everything below it a zero. Once you've done this, you can consider that row completed and column completed. The row because it has a 1 in it, and the column because it's all zeros. Then, you "shave" the completed row and column off the matrix and start again. Don't actually get rid of it, since you'll need it for the end result, and you might need the numbers to generate new ones.
I absolutely despise this demonic method for solving such equations. Love the way you explain it, but a demon will remain a demon no matter how much sugar you coat it with

I've noticed some issues with actually doing the problems, so let me share what I've learned:
In order to solve these, you need to generate zeros. In order to generate zeros, you need to generate ones, but that isn't too hard.
Generating ones is easy, since all you need is an even and an odd number in the same column. If this doesn't work, you can also try dividing a row by a common multiple (E.X: 3 6 6 -> 1 2 2).
When you have a one in a column, what you want to do is move that row to the top, then make everything below it a zero. Once you've done this, you can consider that row completed and column completed. The row because it has a 1 in it, and the column because it's all zeros.
Then, you "shave" the completed row and column off the matrix and start again. Don't actually get rid of it, since you'll need it for the end result, and you might need the numbers to generate new ones.
This guy is the best i have been struggling with this topic
This is very hard 🤦🏻♀️😭
you explained it better than my math teacher, ty
Gosh Jordan why the hell did you make this so complex! lol (sorry I had too)
I laughed an yet I still hate it.
Gauss Jordan is f**ck. How in hell they come of with it, its so complicated way to figure it out what the value of x, y and z. I hate the dum thing.
It can be used also to determine the rank of the matrix.
Finally find the right tutorial now i understand this lesson
I absolutely despise this demonic method for solving such equations. Love the way you explain it, but a demon will remain a demon no matter how much sugar you coat it with
you have a typo in minute 6:00 you turn third row solution from -6 to 6 and at that step the operation is invariant, so it should stay -6
You explain it as easy as making a sandwich. :)
Videos from yt carried me from high school to college thank u ur one of them.
