Algebra 53 - Elementary Row Operations

Once a system of linear equations has been converted to augmented matrix form, that matrix can then be transformed using elementary row operations into a matrix which represents a simpler system of equations with the same solutions as the original system. This lecture introduces the three elementary row operations used to achieve this transformation.

I've seen many matrice videos and yours is by far the best! I love how much detail you go into!

Wow this is amazing. Took me forever to find a decent video and here I am learning from a cartoon professor. The animation saves alot of time and easy to visualize unlike traditional board writings.

how would i know which operation should I use?

[senthilnaathankannappan]

MY PROFFESSOR JUST TELLS SOMETHING AND GOES.YOUR VIDEO IS THE BEST ALL AROUND THE GLOBE

[judilyncodiapit]

Very concise Sir. I appreciate your videos. You've saved my time and gave all the information we have to know. Keep videos coming! Bless you!

[listaja]

This helped a lot. Awesome animation style also. Very clearly explained.

[srenwinkelholm]

Very useful when a textbook is moving quickly and abstractly - thanks!

[Ballsbla]

the best best i dont knw u did it but it just made so simple to understand..thanks

[arifkizilay]

Thousands and thousands of thanks. Superb.

[allesindwillkommen]

Thanks, great video! I can hardly wait for your next one on Gaussian elimination!

[eebsy]

Thank god for Professor Von Schmohawk.

[sora_is_my_dad]

Very nice. I like how you showed how to apply the scale operation in such a clear way.

How do I know which operation to make on each row?

[Femtex]

This is the stuff that always throws me off...at 5:10, where does the 2 come from? The person that made the video just picked a "2" out of a hat and decided to use it? Or is it derived from the problem? Could they have picked ANY number? No videos ever explain where things like this come from so I never know.

[marknuevas]

It was very informative at the same time concise. Thanks for this sir.

[adnantrivedi]

best matrix explanation i have ever seen love it

[Justintlzzz]

This is great and all but what are we gonna use this for in real life?

[Esquizojungla]

Hi. How did you know you had to multiply the third row by negative one third?

[frankg]

Excellent video, animation, and colors to numbers helped.

Hi, are we allowed to multiply both rows before addition? That is, are we allowed to do 2R1-3R2 in a single step?
