Determinant of 3x3 matrix

[@abubakarbobboi2551]

THANKS ALOT, MY MATHS TEACHER MADE IT SO HARD

[@edwinmugisha4159]

abubakar bobboi very relatable

[@PenandPaperScience]

Long live quality online education! :D

[@ChrisHavok]

This is the easiest way to do this and the way it should be taught in the first place. No idea why teachers haven't picked up on this but thank you

[@Spodie]

Math teachers hate him.
Thanks this helped me A TON

[@KraftingKitty]

Thank you so much for this! This is a way better method than the one my teacher explained! I got so confused with that one! This was extremely helpful! Thank you!! :)

WOAH!! this is really easy!!! my prof made it looked like it was some kind of albert einstein mathematics xD THANKSSSSS

[@פרטי-ג3ס]

amazing. you just made my life so much easier..the end to calculation mistakes! thank you

[@15tefera]

god bless you...may he bring fortune to and your loved ones.

Thanks sir

[@binayrawat1866]

Thank you so much love you. It's very helpful., ❤💕

[@mariamihab]

Thank you so much!! You made it so easy!

[@orealz]

I have a weird matrix here where instead of subtracting the green from the red, I had to add them together to get the Det. this is why I hate math, MAKE UP YOUR MIND!!!! If i were in an exam i woulda be screwed!

[@somalifantasypremierleague8548]

wow great explanation pls may u continue posting

[@heatherbluelove]

YOU ARE AWESOME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[@jeremyp3772]

Yup that's a good video right there. Nice explanation

[@GamingYT-sm8qo]

It was so easy
Thanks

[@bie2393]

this is sooooo easy thank u so much

[@zyd7629]

I'll promise I will get an A+ if you be my math lecturer

[@jananpatel9030]

My shitty math teacher taught us nothing. Thanks this is a godlike video

[@lalpeka1379]

Bro i love you so much thank you very much

[@shantanurorin7280]

Thank you so much😍😍😍

[@rajpothare9993]

Thanks alot😍😍

[@shlomimischari3064]

Great video, thanks!

[@Jigneshshah]

Excellent

[@jonmulu6370]

Wow, thank you bro

[@andilemdlalose9926]

why do you subtract the red ones first?

[@elsie5271]

This was very helpful! Thank you so much! :)

[@chorizo4920]

What unconventional sorcery is this???

[@Bunny99s]

It's very conventional ^^. It's called the "Rule of Sarrus".

[@jkizla]

@Bunny83 sounds like the name of a sorcerer to me

[@Hey.its.israel]

@@jkizla lmao

[@jtkplays2190]

Thank jesus for this video

[@munziroon6585]

wow amazing wizard's wand in exams

[@mohanjot.kaur99]

What if the matrix is of some other value like 4X4 or 2X2. Will this method be valid?

[@MrGreenCheddar]

Mohanjot Kaur Can someone please answer this man!!!

[@ADARSHSINGH-dw6ij]

No......its only for 3×3.

[@AdityaMhatre13]

Yes,this is applicable for 4x4 too, but you have to enter the signs accordingly

[@stayfrost04]

I know its a 3 year old comment but if anyone is still wondering then No, this method will **not** be valid. This only works for 3x3 matrix and is known as "Rule of Sarrus". There's one method for 2x2 matrix which is even easier thought. Suppose your 2x2 matrix is
a b
c d
Then determinant will be = (a times d) - (b times c).
For example : Take a 2x2 matrix
3 5
2 6
Then determinant = (3x6) - (5x2)
= 18 - 10
= 8
Hope this helps :)

[@coltboyd22]

Helped a lot

[@elojahjohnpagadut9888]

Thanks 🙏

[@devanshgandhi1276]

Fantastic, this is super easy!

[@sonaagarwal2286]

Fuck u

[@saqlainiqbal8440]

Thanks bro 😍😍😍

[@PoojaKumar123]

Thanks so much! My teacher made this look like physics lol jk...but she made it look really hard!

[@MM3OG]

Okay I'm confused is finding the determinate the same as reducing the matrice?

[@aryavenugopal5979]

Thank you so much

[@glorietatabillabandolon2900]

Thank you

[@kayletorres1040]

I'm confused because my teacher said that we're supposed to add the top to bottom first and then we subtract the bottom to top no matter what the sign is. Help please??

[@elifmeray8998]

Ohh my God you are an amazing sir, thanks for solve my problem. Now, I am going to subscribe your channel. You just deserve more subscribers.

[@cutie6838]

Omg this helped me sooooooooooo much

[@Itachi25894]

It's is only working for 3×3 matrics with positive values 🙄

[@Ishpreet.k_]

Thanks alot😊

[@wwmm8005]

thanks for you😍👌

[@akshayk6691]

How to put sign. While adding

[@dustinsc2023]

great Job

[@sunnatbekmurotov4253]

Wow thanks

[@PenandPaperScience]

For those that want some more practice exercises on 3x3 determinants, I uploaded a video where I solve several such exercises, step-by-step. It might help out some of you :)

[@tapashmazumdar3221]

We haven't done this sums in our school.😃😃😃

[@sigma7208]

Thanks

[@kwilliams6007]

This video stressed me out.

[@darlenee1010]

Thank you so much !!!!

[@jamescuffee6076]

Appreciate it

[@Ammon-Ra]

I used to copy the first two rows under the matrix an do the same thing

[@saththiyambharathiyan8175]

why the determinant is calculated in this way........?

[@dr.adolfhimmler7098]

prima, ausgezeichnet
sehr gut..:)

[@anth0ny45]

NICE!!! Thank you!! :)

[@MithleshKumar-gd6qb]

amazing

[@yasmin0144]

Thanks a lot man 🤘🏽 youre so genius haha

[@friedhelmwinter1911]

Das ist gut!!!Danke.

[@sourayeaturaye2498]

Friedhelm Winter shut up commmie

[@deepshikharaj4261]

thanks soo much

[@kaifiroshid9846]

what's the name of this method?

[@tedtdu]

what is the app you are using for moving, copying etc.?

[@therocker1212]

Looks like paint

[@NE0stormG]

vive Habib.

[@joydipbose1814]

thanks

[@Gulaman_]

does this method work with 6x6 .... I'm getting weird answers?

[@toolworks]

nope. 3x3 only

[@lyndenhall6754]

I LOVE YOU

[@chandraprakashpandian]

Pure sorcery 😂😂😂

[@umm-e-khani6109]

Ooooo thanxxxxxxxxxxx a loooooot🌸🌸🌸❤️❤️❤️

[@sawensh8223]

how can find determinant of 4 by 4 matrix?????

[@thekidwithglasses8756]

sawen sh just add 1 kore

[@ernaveen10]

Wow...

[@tibrojordan1764]

nothing to write on the script....just the answer

[@yemmy8266]

SMH, He just made this look too easily. Thanks

[@valenej.6988]

i love you

[@monspeetsama8688]

Thanks a fuck ton man

[@taureankartik4]

what if it is a 3×4 matrix???

[@taureankartik4]

Pls upload a vid for that too ;)

[@mohab.m.metwally]

not possible!

[@samghazaleh761]

DON'T USE IT, IT DOESN'T WORK ALWAYS

[@her_honey9715]

2.1K Like xD

[@barfyman-362]

Why not explain the motivation?
This is not adding to my understanding

[@kiriskibniewski1883]

I went on an online calculator to check, it said the determinant of this matrix was 24 sooooo

[@danielson0162]

its in fact -32

[@MrDomuksas]

This method doesn't work for all problems. be careful when using this unconventional method

[@UnderscoreZeroLP]

this is fake maths 😒

[@kvrule]

Its all nice knowing a method of how to find the determinant. BUT ACTUALLY KNOWING WHY THE FUCK THAT METHOD WORKS IS WHAT IM LOOKIN FOR AND I CANT FIND THAT ANYWHERE ON THE INTERNET. sorry about that, wasn't tryin to h8 on ur video, im just a little bit pissed off.

[@jeremyp3772]

+kvrule To answer your question.. long long ago a mathematician, or a few of them, sat down and wondered about other ways to get the same answer to a problem, this was one of the ways. it works because someone already did the trial and error process to get the formula correct which gets the answer correct. LOTS AND LOTS of man hours.
