Multiplying matrices

[@ZorrroUK]

Sometimes all it takes is someone to spend some time making a step by step video to seriously help people grasp a concept. Thanks for making this it is such a huge help.

[@esmelinespinal6874]

thanks bill

[@CODandponies]

so, i'm in college, a crappy one that's idea of teaching online is linking to youtube vids, however they did not send me here. i came here bc the ones they did send were awful. and you sir have made my day, and given me another reason to hate my school.

[@ramakrishnabatabyal3003]

which college is this man? seriously, I'm applying and I need to know...

[@American_Trucker_1776]

Oh my god, thank you so much for your help! I have an Algebra II Final Exam tomorrow, and you just saved my life. I had completely forgot how to do matrices until just now. Thank Jesus for KZbin.

[@abbaslangputeh6716]

Thank you a lot sir. You just made my day. I was doing my math homework about matrix and when i watch this, the matrix is actually simple

[@michaellanaux4763]

lol everyone here (including me) is watching this the day before a test

[@ahmedparacha3708]

Lol

[@someone321]

michael lanaux so true 😂

[@tushakarpen5786]

Accurate😂

I'm here 10 min before a final

[@lebenstraum666]

Werner Heisenberg would be proud. Thank you for refreshing my memory from senior high school days.

[@diyajayram1559]

Thank you for the AWESOME video!!! MATH makes SO much more sense now!

[@elliotrainford9696]

Thank you very much. I was having many problems multiplying matrices but you made it very clear and went at a good pace to keep up with. Once again thanks!:)

[@HealingNature]

Easy to follow and understand, comgratulations!

[@KennethCarper77]

Thanks dude, a visual always helps, college textbooks always make everything sound so complicated!!!

[@emilyanschultz7125]

I have a honors algebra test tomorrow and this just saved me

[@kbiolumine]

Did u pass

[@-moved-8237]

Thank you so much I have an Honors Algebra 2 Midterm tomorrow you have literally saved my life

[@apersn9343]

Thank you so much!!!! My math teacher pretty much said “multiply, add, there’s your answer, u hv a test on this tmrw” and left me completely lost

[@MrWeenyTV]

thank you so much! my grade nine teacher is giving my class attest on this and I had no idea how to do this! thank you so much for explaining this so well!

[@samthemessiah9330]

thank you. My school decided to hire the most ignorant, and self righteous man ever as our math teacher. I have learned more in this video than i have in the 2 months that i have had class with him so far.

[@PizzaBoychannel]

Thank you so much. My teacher taught this horribly.

[@aman_xo]

Pizza Boy Mine aswell

[@tqlentless6184]

Samee

[@lilchunnky78]

[@jgc9199]

Mine thought it good but only the basic ones lol but this is good review.

[@ismetyilmaz9481]

1x1=2

[@swolebowl1693]

thank you A) for not explaining this in Hindi like almost all other videos on this B) doing it so well!

[@brickhead125]

This is exactly what I needed for my test tomorrow!

[@butugaeve3300]

I really appreciate it, u just prove my knowledge I was having trouble for solving this problem, thank you very much for your explanation.

[@Thebestpanther]

i really appropriate this i have a test tomorrow and now i have a good feeling ill pass

[@jasondarcey328]

Appropriate?

[@AwfulLottaYea]

[@shaikhginobli2144]

Dude, you just saved my life from ALG 2 disaster :)

[@laughingev]

you just saved my life i love you.

[@DrakiniteOfficial]

Thank you so much for that visual explanation. My class is way ahead of this but I could never grasp the basic multiplication and so I've been lost for the past week. But you forgot to mention the important detail about how the order in which you multiply is super important (A*B is not equal to B*A)

[@EkczHD]

Thank you! My teacher didn't explain this quite well. Now i understand everything. Thanks again!

[@nelsonmin154]

thank you. youtube vids are what's helping me pass my exams, not the teachers :).

[@varun_mhatre]

Thank you for such a detailed teaching. Is any1 having test tommoroe

[@sriyarane8827]

thank you so much for such simple explanation.... in text book it is quite complicated 😄😄

[@siciiddhoore1062]

thank you I hope my teacher learns from you....he really needs this lesson...

[@ModernArnisAC]

3)Moreover, use of heterogeneous dimensions will cause students in a class that are easy to mix up pairs(e.g. left and right, rows and column etc.) to catch their tendency of mixing things up (more specifically Ss often mix up "multiply 1st matrix's row & 2nd matrix's column" as "multiply 1st matrix's column & 2nd matrix's row".) and set correct habits earlier in the learning process.

[@jordantan8832]

Summarizes that hour of 'Matrices' by your maths teacher.. Truly awesome :}

[@TheJesusGirl100]

Thank you, the way you taught this was very concise and done patiently and I understand it now.

[@nybuadi]

All i needed was from the beginning to 1:44 . Thank you very much for the video.

[@anitacaby]

It's the day before my maths exam. I should have found you before

[@ahamedjunaid01]

Procrastinators Assemble!!

[@mohamedadam5379]

bruhh i was confused on this for a while my teacher does not know how to explain this really helped alot thank you!!!

[@Flakis992]

You saved my live!! Thank you so much you are great at explaining!!

[@merrilycava4326]

Just watched this video the day before I sat for my term 2mid term maths paper..thanx for the help

[@rachelromans1]

Thank you. My textbook was very confusing, you explained it very nicely and simply.

[@gabealberro6081]

Thank you, your 8min vid is a lot better than my 50 min class

[@Liiteesmo1408]

Pls tell me what you are using screen recording and..... Tell me that software

[@libbyrogers45]

My teacher explained it several different wrong ways which made me extremely confused. Thank you so much for clearing up everything!

[@ristotenno6438]

Thank you for the design - it allows me to just copy a picture of the video at it's end point and save it to a note, but by just looking at that I have everything I need! tHanks!

[@kelvinfeliciano]

I am confused because you said in the beginning of the video that in order to multiply the inside number must be the same. [2*3] and [3*3] but if we change the order [3*3] and [2*3] the inside number are not the same anymore. but since is multiplication I believe it should not change, or how do you know which order the matrix should go. Thanks

[@anmolc2]

In matrix multiplication AxB is not necessarily equal to BxA. The order of multiplication matters. Here if u try to multiply the second matrix with the first(ie change the order) , multiplication will not be possible

[@kelvinfeliciano]

Anmol Chopra thanks man, I worked out and saw that it does not work.

[@thomaslewis247]

Thank you for being so easy to understand. You made that very easy

[@vicevizz4812]

Thank you for saving my LIFE !!!

[@franchiraperalta9202]

Your videos are so helpful! thank you so much!!

[@CJKpop4ever3]

Thank you so much!!! took me forever to understand matrix multiplication untill now :D

[@ramose83]

What I realy like that you do it step by step even thogh that you may repeat the steps again and again; excellen thank you very much.

[@dilshodakomilova7204]

I also have a math exam tomorrow . Great video thanks so much

[@riotchica4414]

Really helpful, Reading how to multiply matrices in the book is confusing, but you cleared up any confusion, thanks much.

[@UmanathKandel]

so nice of you for make me clear understanding

[@DianaRodriguez-zm3ef]

Hello, I may be wondering if does it apply too in subtraction? my teacher gave me a same set of matrices. They are equal in set, but I dont know if it applies when it comes to subtraction not multiplication. Thank you

[@dustinsc2023]

Thank you for making it simple and using colors. Great Job.

[@TheFunnyman1233]

Thank you so much. I have a geometry final tomorrow and I just couldn't get matrices and soh-cah-toa. I think I might pass now. :)

[@ssbig7524]

Does it will wrong if 1st matrix column will not equal to 2nd matrix row🤔🤔🤔

[@harshlobin2998]

love you bro you save me you are better than my maths teacher . 😊😊😊

[@45aayush]

The concept is very Well explained. Liked it. Thank you.😀

[@melodynel6352]

Thank you for this video, was really battling with this concept and your video cleared up my confusion😊

[@celestel.8507]

Thank you! This honestly helped me so much!

[@muhammadumaranjum.official3924]

hey what about when we have all variables in both matrices? 4x4 both?

[@jamesliai573]

thanks you professor .u have gave me 6 marks in my final exams.

[@wilsonstrickland8967]

This was a very useful crash course; Thanks so much!

[@fabiogerussibueriis]

Very Well Done!

[@s.h.01]

Great work I should start learning online instead of wasting time with teachers who can't teach

[@RJYL]

Clear representation never seen before,thanks a lot.

[@enisbardhi3720]

This helped so much.Thank you !

[@MuhammadAli-ui9kb]

Oh my god! You just saved my life.😁thank you so much

[@josecastillo1888]

Thanks to you I could do my Homework

[@jackbotman]

So to make it visually easier, you could flip the first matrix clock/counterclockwise so it lays on it's side

[@samhitabandyopadhyay2568]

Thanks it really helps me to overcome my school exam

[@VisionaryFire]

2:54 Why did he add and not multiply? He never explained why you add them...

[@d-shiri]

The best explanation ever :), Thank YOU

[@smartblond9962]

Thank you very much, you helped me a lot. I understand it now, u explained really good. 😊

[@swiftilicious13]

I bet that this video will be easier to understand than my teacher explaining this tmrw.

[@rosvienapigkit5984]

thank you... you've helped me a lot.

[@ammaramirul6423]

Thanks dude...love you from malaysia

[@opreese]

I think matrix multiplication applies to 3d rotation but I never understood matrix math. If you can, please make some videos about how matrix math is used in 3d rotation and how it prevents gimbal lock. Thanks, Owen Reese.

[@lil_tesla_69]

Hi

[@kellykel4177]

Tank you very much now i have understand this matrices ☺

[@richardopiah5107]

Thanks for doing this. It was really helpful.

[@strikerotr]

Well done , best explanation !!!

[@thestovietunion790]

I am trying to learn graphics programming and the 3d rotation matrices seemed wrong to me (I got matrices instead of point coordinates as a result), now they don't. Thank you.

[@samneuenschwander3897]

Thank you so much I had a sub try and teach this to my class

[@brianmphanje7563]

Appreciated, good lessons

[@srikirancapri]

I won't use this you tube If I had a teacher like this teacher

[@saidmohd6377]

Thank you very much

[@5injl]

THNX SO MUCH. THIS WAS SO HELPFUL

[@justjacqueline2004]

We have spent a a long time with a lot of examples on this one subject and still the vast majority of us failed this paper(87%),lots of examples will now be thrown at us until we get this and less than a year to our finals-ouch!Thanks for the help.
