This looks sus! Is the multiplication of matrices this easy? (Reddit r/mathmemes)

New mechanic just dropped!! 196-182*0.5=7!! Most Redditors didn't get this! https://youtu.be/AQiGPtbZo0I

You "broke" the pattern with a green pen. Black and Red alone were expected. We entered another dimension/world? Thank you for the video.

It works for diagonal matrices because of all the zeros. If it works for anything else it’s a happy accident.

Love that "oldie but a goodie" simplification of 16 / 64.

Bprp helped me so much by teaching me calculus and now he is teaching matrices? Huge W

These are the math equivalent of Dad Jokes.

I love these "wrong way but not really" rules

In the beginning he goes "ok, so let's discuss what's going on" and i initially thought he was saying "ok, so that's disgusting" and really i agree

r/mathmemes mentioned 🔥🔥

It's actually product...

Tomorrow is my exam i was studying matrix and determinants this notification pop up

I’m self teaching linear algebra and this video is super simple and clear to understand! I would love to see more linear algebra videos!

Looks like a tini-mini 6th grader tried to attempt this logically 😂😂

I always hated how matrix multiplication is taught. Rows times columns errrggh.. what? Where have I been, did I make a mistake? I always get confused. So I have devised a better method. I imagine the matrices are rotated 45 degrees to right and the result matrix is like a lego brick down between them. That determines its size. Then I imagine the numbers are like balls in a tivoli machine, just waiting to fall down to their place, just block by some imaginary obstacle. Then I release both of the obstacles at once and from both sides numbers start falling in their respecive line. And the numbers that hit each other are the ones that multiply and all the numbers that hit in the same place are added and the result is the number in that place. And then I just rotate the resulting matrix 45 degrees left and put it where math teacher wants it. I don't know if I explained it right so you can imagine it, but this is what I do in my head to prevent myself from making mistakes so I don't have to think in terms of confusing rows and columns. There is also a way to do the same thing without the 45 degree rotation, if you just imagine the right matrix is just above the left matrix but just to the right, so the resulting matrix is just right of the first and just below the second and the multiplied vectors are basically just intersections..., but the gravity thing kinda helps me... I guess I better make a video. :D Maybe one day

Thank you

I wish I didn’t need more of this, but I really do

Thank you for teaching me how to multiply matricies! I tried it with some random numbers, and it worked!

That'd be the Hadamard's which is just fine…

5:00 since regular multiplication is associative, can we add another 4 equations from multiplying matricies in reverse order (AB = BA = C, C is the wrong way)? Ok, some of them doesn't matter, but seeng AB=BA would be also invalid in general

Thank you for helping me on calculus 2
