Hello Mr Whitt! I used to watch your tutorials back when I was in 8th Grade. Now I’m in 11th Grade, It’s Online School so I’ll probably have a hard time and would have to rely on your tutorials again. Can I ask what notebook apps you use so I can use it too on my iPad? Thank you!
Thank you so much Mr. Whitt. I love all of your videos. This was an awesome video on matrices. I’m guessing the key to solving these is by adding and multiplying rows in such a way that you don’t undo the zeros and diagonal 1s that you have already put into place in order to achieve more diagonal 1s. I always struggled with deriving the right combinations. Is there a technique that you recommend?

Great Video, Mr. Whitt. I used your videos A LOT in my virtual tutoring sessions. The time stamps are extremely beneficial. Keep up the great work
Thanks 4 sharing Vertoria! I appreciate your feedback! 👨🏾🏫😁
Thanks Limitless Math! Great 2 hear the videos and timestamps are helpful! 👨🏾🏫😁
Thank you very much Mr. Whitt. I love all your videos. I'm learning as quickly I can. RED BOX IT! 😂😂😁😁
Thanks Mr. Whitt!
My pleasure NWD 38! 👨🏾🏫😁

Yes, focus on completing one column at a time and you can use that method consistently. The first few examples demonstrate this strategy.
Fort Bend Tutoring I will utilize that technique. Thank you so much for all the hard work that you do to produce these videos.
