I have to say, you are a brilliant teacher. You present it at the exact speed I like to consume it. And your presentation style is very clear, have you worked in the theatre before ?

I think it's just an error. He only affected the second row in that step, hence first row must have stayed intact. You can obtain the reduced echelon form of A by substracting -3/2R2 from R1 if no change in R1 at 6:46 is made.
It seems he just did an extra step without saying anything. If you add row 2 to row 1 you get that change, it was a really quick step that made it more readable so he just forgot to mention it.

Just found this channel now and it's soooo good, really high quality and clear teaching
Thanks so much! Still a long ways to go to finish my linear algebra series, but I'm hard at work!
Thank you sir for your exceptionally clear explanation !❤
Thank you for watching!
Very clear about reduced row - echelon matrix. Thank you sir!
Glad to help!
In finding the RREF, how did you get the top row to change into 1 3 1 from 1 3/2 2?
Exactly
he added R1 and R2 in the same step he just forgot to explain
I added Row 2 to Row 3. I don't know why I did that or why I didn't mention it in the video, my bad!
Thank you for such a clear explanation! Helped me a lot!
Glad it helped!
6:13 i love how you clearly showed every step involved ,i am now subscribed
Thank you!
pure quality, keep the good work up!
Pure quality is exactly what I'm going for - thank you!
Very well-explained! Thank you so much
Glad it was helpful!!
Thank you very much for the clear explanation :)

Thank you! I did actually work in theatre for 5 years as a teenager!

@@WrathofMath Whoa that's really cool! I've never been to Santa's Village, but it would be neat to visit sometime.
6:49 Row 1, how is 3/2 turning into 3(which needs multiplication by 2), and 2 turning into 1(which needs division by 2).
yes exactly i was coming to write it in the comment section
What a great easy to follow explanation
Glad it was helpful!
I thank you. You helped me. I was struggling to find different between row echelon form and reduced row echelon form😊
Glad I could help!
best video by explaining practical usage
Thank you!
Awesome and clear Video.keep it up sir.
Thank you - I will!
thanks for clear explanation
thanks a lot, you explained it best with most clarity
Glad it helped - thanks for watching!
Such a great vedio on REF
Thank you!
How did you get the top row from 1 3/2 2 to become 1 3 1?
Same question?
I think it's just an error. He only affected the second row in that step, hence first row must have stayed intact. You can obtain the reduced echelon form of A by substracting -3/2R2 from R1 if no change in R1 at 6:46 is made.
It seems he just did an extra step without saying anything. If you add row 2 to row 1 you get that change, it was a really quick step that made it more readable so he just forgot to mention it.
I came to the comment section for this exact question. I think he made an error.
You explain so good I don't know why you left some steps out of the video. The exercise is not making sense anymore
Hey buddy love this tutorial. 😇
6:50 How did in mid bottom matrix a12 became 3 from 3/2?
6:54 how did 3/2 and 2 become 3 and 1 ?
Thanks a Ton!!!
Glad to help!
so is this like solving a puzzle, theres no one way to do it, end goal being reduced row echealon form?
also when do you know what to use like when do you use R1 R2 vs R3 solving?
Basic Rule-there should be not a non zero element below the Upper non zero element in each rows
Does it mean every individual needs to get the same answers in finding ref of a matrix
I guess only your playlist can save me
Did it end up saving you?
@@PunmasterSTP indeed
@@Nova96v Awesome! Did you have to take another math class after linear algebra?
@@PunmasterSTP if we're talking about the topics of linear algebra covered in his playlist, no I did not have to go anywhere
@@Nova96v Sounds good. Did you have to take any other math classes in your college or university, or was LA your last one?
Nice vid x
Thank youuuuuuuuuuuuuuuuuuu
Glad to help! Thanks for watching!
If there were math games, you'd make a great rref! 😆
loved it
Thank you!
How did 3/2 turn into 3

You speak English very fast but your explanation is good 👍.
Thank you!

6:49 Row 1, how is 3/2 turning into 3(which needs multiplication by 2), and 2 turning into 1(which needs division by 2).
reply under @karenwoodruff4813 's comment by @ikersanchez8222 fixed and gave the correct answer for it.
I added Row 2 to Row 3. I don't know why I did that or why I didn't mention it in the video, my bad!
@@WrathofMath You mean you added Row 2 to Row 1 not Row 3
