WOW, ILL NEVER FAIL THIS MODULE EVER! U MADE MATRICES EASIER AND FUN. THANK U SO MUCH, SIR. I WAS WORRIED THAT I WONT SURVIVE...KEEP IT UP

“Of course easier said than done” lol btw thank you sir!

Took you 9 minutes to explain what it took my teacher more than 3 and i still didnt get it to now, THANK YOU seriously

[MrStanislow]

If I understand your question correctly, you're asking if we are allowed to leave negative 1. The answer is no. Every entry in the original matrix must be turned to either a zero or a (positive) 1. Negatives are not allowed. The order at which you do the operations is entirely up to you. There are some general rules and guidelines as to what order to do your elementary row operations, but you can arrive at the answer by traveling down a number of different avenues. Hope this helped. -gs

8 years later and you still might help me pass my math finals

the most calming part about this video is he sounds like the dad from Bob's Burgers

No disrespect if this isnt the way you mean to teach, but i really like being taught like a 10 year old. My lecture is just so terrible, incredibly intellegent guy and a really nice bloke but my god in lectures i struggle to follow him saying hello let alone teaching us, this was a sweet video cheers :D x

[flik-films]

It's so easy now, kinda fun. Thank you!

[michaelkamau]

ure a natural man...THUMBS UP...plizzz just remember to write the whole addition beside the matrix...R3 plus R2 n the others

[ethanreker]

Thank you! Great explanation that is short and to the point.

[HugoMartinez-oiey]

Hey man, in the very first step, why don't you swap R2 with R3?

[mohamednawaz]

THANKS ALOT, really helped, at such a critical point.

I thought this method is called augmented matrix? and ERO need to come up with E1E2E3?

[MSTARLIGHT]

So basically we just have to find the row operations by ourselves?

[jacquesvellaborg]

Thanks for uploading this, helped me a lot 😁

[SillJexster]

What to do when the variable is negative? do we need to make it to 1 before continue?

[TheOwnerPO]

@7:39....Why not multiply R3 by 2 then subtract R1 ?

[muskaansaifi]

Your strongly thank you ... I was very tensed while doing this ... Luv u

THANKS A TON YOU'RE THE BEST DUDE
