it's a relief when i search for something and this dude's video appears

[leetoniadancecentralldc]

I'd rather give you my school fee. You've taught me everything I know.


Wow, thank you for likes!

[sammyomoto]

What's with the thumbs down people? He is the best tutor ever, seriously.

[ounie]

You've made this so simple, I can't believe how simple it is. Thank you so much.

[esdan]

I never understand stuff when we learn it in class, but I don’t sweat because I know he has my back.

[aliyaismael]

dude I owed you everything, without you I would've been a college dropout

[Sibasish]

Face reveal please, it is important to know the person who has taught me from junior school to high school to university

Had a 3x3 on my maths exam last week. Thank you for all your information, got a High Distinction, top marks in my maths engineering class :D

[appiahisaac]

Wow!
This is the first time of learning 4x4 matrices. Thanks so much. You are the best tutor online.

This helped me prepare for my end of year exam and I aced it, thanks a lot man. Really, don't think that I could've gotten through my second semester exam without your videos. Which makes me wonder how you got to understand them all considering how complex they are!!!! Anyway thanks!!!!

I hate
When someone dislike his videos
Man is genius and deserves every bit

MR. Organic Chemistry Tutor, thank you for an excellent video/lecture on Finding the Determinant of a 4x4 Matrix. This is a classic problem in old fashion Linear Algebra/Systems.

[cervixcrusader]

This channel and Khan Academy got me through high school and now University

[VirtualTech]

Me an computer science student watching this after I forgot everything taught to us in 10th grade

[pockyrice]

bruh im taking pre calc online and I literally came across this today, but it’s a 3x3 matrix and the HW is due today.

I did not expect you to make a tutorial on how to do this. Freaking clutch man!!

[adhelrechngorrech]

You are the best online teacher. You really helped many students Excel in their exams. Thanks

[chepaulinus]

Wow, now I can find the determinant of a 4*4, thanks sir.

[izdiwvr]

how i wish i met you earlier my first degree program, you really makes maths lovely

[hadeerrashad]

EXCELLENT explanations!! And thanks A LOT for telling us about the website

It may be good practice to draw straight lines for determinant instead of square brackets. 5*[A] means different thing to 5*|A|
