This concept is so easy. As a pre-calc student, I'm glad to get a break.

[@harmanjotsingh4230]

Very true

[@seabasschukwu6988]

How’s school going?

[@drawingfreak9936]

Bro I’m learning this in honors algebra, Im in 8th grade 💀⚰️

[@notyourlife-w5b]

@@drawingfreak9936 yea there is matrix in middle school (for me secondary school)

[@fred-nyanokwi]

True he is an excellent teacher

[@georgesadler7830]

MR. Organic Chemistry Tutor, this is another solid introduction to Linear Algebra and Matrix Operations. Linear Algebra/Systems is built into all technical classes.

"Thanks for watching" and Thank you for teaching♥

[@datpham31415]

There is a gap at the end of every of your videos that's great. I have time to move on to next video.

[@tamandabasikolo760]

Love your videos...you explain clearly makes it easy to understand and get the concept

[@rosangapachuau7841]

😂😂. I'm just a class 12 student who takes history subject. After watching his videos, I going to shock my friends with my maths skills.😎😎

[@rugiraemmanuel-h6k]

Waoo, you are qualified to be a good teacher

[@kaylia9122]

At 6:38 aren't you supposed to subtract and not add them? I'm confused since you said 5A-6B..

[@jirenthegrey3075]

That's because he's multiplying the matrix with -6. When the negative is taken away, it gets replaced by a positive Extra note: When a positive is taken away, it just remains positive

I feel like you have stereotypical boston accent and I love it.

[@muhammad14u2c]

still the best voice on youtube. hands down.

[@kaasegbertyoh6105]

I understand it very easy.

[@cyndifeeney1049]

Please jog my thinking with why are we multiplying by 3 and 4 and what determined the factors for your second example. Thank you.

[@apacherulz5231]

Just example values! Could be any number

[@SyedAshfaq-ok1xc]

You sound like Sheldon cooper sir , your lectures help me alot

More like young Sheldon

I love your vedio sooooooooo much, plz keep doing it!!!!

love your videos .. you explain so clearly thank you so much

[@mattcapper3705]

who else doing this for online learning

[@AberClare]

Thank you so much for the clear explanations

[@olamileanongod_1]

How about if I have this problem? A=[2478] and B[1111] [1023]. [2222] Find 1) 3A+2B. Ii) 4A-7B

bro tried to get his answers from a yt comment xD

Thanks my teacher

[@Travelwithme1564]

Thank you ❤

[@NOWRTX]

thank you of great work

[@prajwalkarigoudar2769]

I tried to solve it before him and ended up with the wrong answer lol XD

[@semanget5840]

It is so helpful video keep it up

[@b__5223]

can someone explain why at 2:14 a plus sign was put when the question says minus?

[@fabrica12dz64]

imagine it like this in place of -6 put a 1*(-6) and u multiply by the -6 inside the matrix and keep the one outside then if its a 1 u dont have to write it since everything is multiplied by 1 in the first place

[@rayhanahmed3702]

What he has done there is multiplying -6 with +1 = +1(-6). And because 1 multiplied by any number returns the same number we don't need to write+1(-6)[B] hence +(-6)[B]. Before: -6[B] After: +(-6)[B],,,,Since +(-6) = -6

[@ScottySR]

In the previous matrix video you showed multiplication which at first glance seems exactly same as scalar multiplication. What's the difference?

[@adhirajsingh1806]

nothing, that was the same thing

[@ELLEMADWIGHTEMMANUEL]

3:30 5A - 6B and then you add why?

[@AdnanAmir69]

Cuz it's easy that way, either way if u add or subtract the answer will be same. He explained it at 1:48

[@AngelDengMayak]

Thanks you so much

[@wylercambod2955]

Is it possible that we can add or subtract matricis with different sizes?

[@mamadousjallow313]

Naa, you only add or sub matrices with the same sizes.

[@believeonsecretstudy6050]

thanks sir

[@patrickinocencio2305]

Guys "LIKE" the video pls. Don't forget it

[@yabsira1321]

Why are we multiplying it with 3?? Is it constant for every operations

[@nihatdonmezov8354]

No

[@conversation2581]

its just a scalar and every real number can be a scalar

[@areefmohammad6581]

Nice Bro..👍

[@LuNa-tz3lq]

at first I am confuse why did he add but he explained it at 1:48

[@tombrider8928]

Thank you 😊

[@LillianMulenga-x3y]

Multiply a matrix by a scalar. 2Aif A = (3_2)

[@rafayibrahim352]

bro i love you thank you

[@nethanchrishanesilva2050]

Gay?

[@zoeybuyig1981]

Like a chess one sign could change everything 😅🎉 thank u for the video

[@Kr_basha]

Danke viele

[@believeonsecretstudy6050]

it has easy to understand

[@kanzuk-637]

Why did you choose 3a and 4b did you randomly choose and i can choose any digit or is there a method?

[@raifakabir3657]

tysm

[@sunoocutie6305]

isn't -6+-21 is equal to -27? correct me if im wrong

[@shipasinghhhh]

Nice 👍

[@petriceking1715]

How did you get the 3 to multiple set A and the 4 to multiple set B ?????

[@yamsang0__0]

so much more concise than my lectures lol

[@heerraval528]

Well, his voice isn't a joke🫣 I mean like, I would understand nothing, but listen to his voice😭😭😭

[@Animx185]

😂😂

[@NgongMunang-vb1ox]

Pleas o wish to ask where the 3,4 they used in multiplying came from

[@gangadharkulkarni8151]

Not understanding

[@sharpnighttoo3667]

i swear this helps but when they through in a x or a y out of no where to mess your day up.

[@hussainjaishan2225]

Why does the sign change subtraction to addition

[@ValinamaVele]

Understand well... directed numbers rules is always used?

[@believeonsecretstudy6050]

Nice sir

[@christophernongbet4611]

Why do we need to multiply first for 5a and 6b instead of sum up within a bracket

[@ronaldonongbet620]

According to that time period of 1:54. You said that if we ×ply the matrix B to it element. According to you, you multiply by -6 to the element of "B". What if you multiply it only by 6, So can you show me how will i proceed by multiplying only by 6 to the element of B

[@gloriagrant8060]

Pls solve -4a-3b

[@mellie9120]

My q is why cant you multiply it like that both the matrices together like you do in addition

[@AbidxArman]

3:28 15+(-54) = - 39 WHY??

[@oxkia648]

because you could switch it= -54 +15 54 minus 15 is 39 add the negative and boom! -39

[@noesaidfuentescortes69]

Madre mía esto no lo vi en Mexico 😩

[@HSGMministry]

❤

[@zen3745]

3:22 you mean -69

[@jsliced_ramii]

You're wrong though , since you're adding two opposite sign numbers right there

Me happy, me want potato

Potato

2×3 3×3 ka they are is not same matrix

[@robertcharles1195]

After multiplying 5a-6b aren't you supposed to subtract why did you add

[@Z-Boson]

What's the answer ah?

[@Hunni427.]

because he multipied b matrix with -6, thwts why +

[@jowaynenicholson4056]

​@@Hunni427. Was the B matrix negative? I don't understand.

[@jowaynenicholson4056]

​@@Hunni427.Is it a rule that even if you have the -6B you must still add the matrices?

[@Hunni427.]

@@jowaynenicholson4056 do you have any other sorts of contact other than KZbin comment, I'll explain better that way

[@cocomatef]

why you set plus sign between the to matrix and not minus?(2:16)

[@freeguylota]

I love when he makes petty mistakes to show that he’s till human

[@ELXIXXX]

Yeah we all are pal

[@Dannydrinkbottom]

Why are we adding at 5A-6B? That part confused me.

[@domferno]

why yuh suh blasted weird

[@fofouEsther]

Thanks for the clear explanations
