I never add comments but I just wanted to say that you've literally had my back since day 1. In high school I have been watching your chemistry videos for years, and your maths ones too. Now, years later, while already in my second year of university studying economics, you still somehow manage to help me with so many things. I genuinely cannot thank you enough.
My man, I have been pursuing an Electrical Engineering degree since 2017. You've literally saved me during home works, tests, and quizzes. From Trig, to calculus 3, to linear algebra, to DiffEq, and now even into systems and signals! You have helped me and so many other people dude! You're quite possibly the most underappreciated academic asset the information age has ever seen! THANK YOU!!!
This guy is one of the most important persons in this nation. The government should pay him he’s carrying the whole country at this point. I was in the library the other day and listened to his voice because someone was watching a video. Now I’m here watching one of his videos. Been helping me since high school. This also proves professors should do a better job teaching 😂.
I can always find a better explanation here than from any of the math teachers or professors that I have ever had. I study Computer Engineering and you've helped me through every calculus and electrical engineering course, I don't even take chemistry.
Found this channel during my school exam days, then again at college exam days, then again at my university entrance exam, then again during my 1, and 2 years, and now my exams are here again, and so is your channel. Just wanted to say, you are doing something that is highly appreciated by all students and non-students. Thank you!
I though Cramer's rule will be faster but damn it is longer... I suggest for those who want to resolve 3*3 to do x=A-1*b where A-1=ajoint(A)/determinant(a)
The best channel about chemisty I recommended all students in my university to watch this channel Igot high mark in (innorganic) when.i studied on your videos
I love this man with my whole heart. I have been watching your videos from my senior year at high school and now I am a third-year Computer Science student. Thank you so much for your help!!!
someone actually thought about this... like Cramer was like okay im just gonna put all these numbers her select one delete the others multiply like that, then add them and in the end exchange a with d b with d and c with d and there's the answer
basically, it's how it works in real life. Teacher gives you themes and some general direction and after it's up to you to look for a good source and understand it. If ya not agree probably math is not your thing.
Your videos are so helpful, you have no idea the impact you're videos have had on my studies and furthering my studies... you are a star and truly grateful to have come across your UA-cam channel.🙏
Very nicely explained. One minor quibble: you are using the notation for matrices (the square brackets: "[" and "]") when you should be using the notation for determinants (the straight lines, or pipes: "|" and "|"). But everything else was great! 👍
Thanks for the clear and concise explanation. My teacher went over this in 45 minutes and I was more lost than when I had started looking at it. Now I can see that it's simple but just takes a fuck ton of time.
Dude Thank You So Much For Teaching, you are amazing and simplify complex subjects and make it look effortless. I was learning systems of equations with 3 variables and had to use substitution and honestly it’s a pain in the ass not because it’s hard, but because it’s a lot of work and basically takes up an entire page. Thank You So Much!
im a romanian and we do this in math in 11th grade. i wrote cramer on youtube, without anything else, showing me results in english. checked the video, checked my notebook, realised how MUCH MORE complicated the method in this video is.
Following this video, I was able to solve my problem with different coefficients! Thank you! You have been one of my best references (tools) since 2018!
I don't know why I always wanted to watch your math, Chem and physics vedio I'm always glad to watch your videos it is the best i could say i give you thums up for your time and effort
I really don't know how to thank u sir..u just saved me b4 exam..I found your channel this yr n I couldn't help commenting that U r the best...I repeat..THE BEST😢❤..
Thank you so much. Saved my life again. My teacher made it so weird and confusing by adding and subtracting columns and rows to get 0s which got me weird numbers. Thank you once again
ok hold on, ik this is probably really late to say this, but your videos help me out in math way more than I expected, and it's been saving me so much trouble. So thank you for releasing these videos to help me undserstand :D
Your video helped me a lot, but your voice is so soft I had to turn to volume to almost maximum, then in the middle a bloody advertisement came in while I had my earphone on with maximum volume I'm half deaf now😂😂😂
i literally watch this video for my mid term test last year and here i am right now watching the same exact video one year later for the exact same reason goddamit i failed my test :)
That's cause the actual determinant rule per term is: (-1) ^ (i+j) * a(ij) [Determinant of minor (Mij)] where i = the row and j = the column. Usually, when we evaluate this, we get the order as + a - b + c etc... Hope that makes sense!
Niiiceee video! i learn a lot! just one thing, try to put the determinant symbols (the straight lines) instead of the matrix symbols because i tried to do the excercise and i made an scalar matrix multiplication instead of the multiplication of the scalars by the determinant of the 2x2 matrices

This made a lot more sense than the pages of notes we got from our teacher... thank you
I agree with you...
The notes I Also received didn't make sense
yes
You're right! I also came here because this person first clear basics and then tell rules or something else. In this way it's easy to remember
My lecture is an ass he keeps the notes for himself

You have literally saved me. Thanks to you I actually have a chance of graduating in December! Bless you. Keep up the wonderful work

I have been re watching my lecture for a couple of hours not understanding. I watch your video once and it all makes sense. Thank you so much.

Literal LEGEND!!! Helped me with my maths assignment.
Bro is a lifesaver... I have a test in 1 1/2 hours and I had no clue but this makes perfect sense. Gotta love it
This just saved me lots of stress ngl; you explained it so much better than my professor lol
I'm in 7th grade and I just started learning this today, and this video helped so much with the hw, tysm!
Bruh you learning this in 7th grade?
I doing this in 9th and thought it was semi difficult
Nick Ballas lol it’s quite painful, I took a summer course
SoundlessDestiny it is really hard
i learned it in 7th too. i'm in calculus now, and thought that i might review it for fun.

one of the best if not THE best video made on matrices!! keep up the great content!
I bet I'm gonna have to stick to you for much of my math life. What a tutor you are! ❤
best example of cramer's rule applied on linear system on the internet, very well explained, thank you.

In africa we learn in grade 9
I just go to class to note the topic and come back here.....you are a thousand times better than lectures

Thank you very much. Just like every video Ive watched from I found this very helpful
All addition, subtraction, multiplication, and division, but quite a complex method. I like it!!

Thx so much man. Life saver right here
easy, understandable, comfortable for cognition. wanna just thank you
@2:47 why is is a1 MINUS/NEG b1 PLUS c1? what determines the PLUS or MINUS/NEG at this stage?
i am curious too
That's cause the actual determinant rule per term is: (-1) ^ (i+j) * a(ij) [Determinant of minor (Mij)] where i = the row and j = the column. Usually, when we evaluate this, we get the order as + a - b + c etc... Hope that makes sense!
Maaaaaaaaaan you're so awesome thx for the solution of this cramer exercice !
Oh man thank you so much, you are a blessing❤️❤️
Niiiceee video! i learn a lot! just one thing, try to put the determinant symbols (the straight lines) instead of the matrix symbols because i tried to do the excercise and i made an scalar matrix multiplication instead of the multiplication of the scalars by the determinant of the 2x2 matrices
these video lessons are very beneficial to solve my math problems and it is more convenient to understand the lesson than my teacher in the university
Sure comrade, I wish I could meet him so that I express my sincere appreciation and gratefulness. Thanks 👍
