I might just start using japanese math with multiple colored pencils and bill by the hour..

Haven’t seen a few of these before. +1 and happy new year!

I particularly enjoyed the last one.

I love math. I regret not doing undergrad in it ? ? ? ?

#9 this is actually (more or less) how pythagore was proven by ancient greeks

I’m a 40 yr old mechanical engineer and the visual Pythagorean theorem blew my mind.

#1 y=log_a(x) is upside-down, y=sin(x) is also flipped

Well now I officially feel stupid for the new year thanks

The “Japanese multiplication” is just a visualization of longhand multiplication.

I just passed calculus with a c. Time to forget all of this.

Better: transform the pentagon to one big triangke first.

My slow brain on New years day: Why are there 5 equations and four lines. Ah! for +/- sqrt

I posted this to imgur a LONG time ago (I may have even been first lol) +1 happy new year!

The "Japanese math" example always irritates since it's completely ridiculous when you move up to something like 87 x 688.

I can't believe I used to understand this

Such an underrated comment
apneax3n0n
i used to understand and love it . had stopped using it since i stareted working in a unrelated fields. 5 years later i found my old ->
apneax3n0n
books and notes . i could not understand a single line of my own writing. (analisi matematica 3 fuck that shit).

Me and math were never good friends. I can count on a hand with 4 amputated fingers how many tests I scored positive during middle and high.

Just reread a paper I wrote in grad school and it took me a while to understand it. The struggle is real

Ok but how do I do taxes?
Firekeeper00
Bro I'm studying it rn and I still don't understand lol
POGassultraboot
You understood?
apneax3n0n
when u do it every day it's not that hard. stop for 6 months and it's ununderstandable
POGassultraboot
That’s cool. What job was that?
apneax3n0n
I studied mechanical engineering but I work as a software developer so no complex math is involved
POGassultraboot
Gotcha. Sounds pretty cool.

Dont you just mean derstandable?
apneax3n0n
no it was not https://www.yourdictionary.com/ununderstandable#:~:text=Not%20understandable%3B%20that%20cannot%20be%20understood.
apneax3n0n
wait the opposite of understandable is just derstandable ? this makes no sense. i mean if the prefix un is for the negation "unbelievable"->
apneax3n0n
"unhappy","unfuckable" ... you are thelling me the understandable is the negative version ? i mean the clear word in getting things->

Nice! Did you know #2 can be done completely by hinged dissection?
Werewolf4619
I feel like #2 made things way harder than necessary after getting the rectangles.
animatronicChristmasChickens
You can show how to disassemble and reassemble. #2 seems like it's going to do that but doesn't quite
Snooj
Even before that. Once you have the triangles you can calculate their areas, add them together, take the root. Done.
InkyBlinkyPinkyAndClyde
This is what I was thinking. I guess it's a nice proof, but if you have the actual numbers all you need is the area of the polygon.
TheDarkNerd
Though I think the idea is that this can all be done with a compass and straightedge.
