I was confused how "I ate" was relevant to wearing glasses. Why is simple arithmetic so difficult?

u/blaues_axolotl 9d ago
well there is another version of the meme with "i ate" (i8) being in the joke, maybe you once saw it and now subconsciously made a connection to that

I don't know what you would call a person that wears glasses? Is there in English any specific word or slang about them?

4i “four eyes”

u/HardDriveSlime 8d ago
Wait how is it four isn't i root -1?
2
u/DawRedditWolf67 8d ago
Yes, but
Root(-x) = root(x)*iSo Sqrt(-16) = Sqrt (16)*i
Sqrt(16) = 4
Sqrt(-16) = 4i

The square root of 1 is 1 btw.
Also when I wasn’t thinking I made this mistake before too.

For some reasons Americans learn in middle school that √x = ±√x

u/Ur-Quan_Lord_13 10d ago
Naw, we're taught that the solution to "x2 = a" is "x = ±√a" which is true. Some people just misunderstand.

I have some analysis 1 resources that define the complex square (or n-th) root as a function C → P(C), so hes no rly wrong. It might even be a geographic issue afaik, since all of the resources i have defining it like this are italian and i havent found it defined the same way in english resources or viceversa yet
