Anyone interested in a math thread?
Post questions, get answers, discuss topics, etc.
I'd like to discuss something: p-adics.
These are another way of extending Q, instead of the normal way of extending it to R.
One thing I wanna know: How different are they from R? Like, are there numbers in the p-adics that don't exist in R? I'm not sure of this, but I think all the algebraic numbers in Qp are in R.
...
That is correct.
And in the p-adics, this also holds.
Think about x=…999.999… (where the nines go off in both the right and left direction).
10x = …999.999… = x
10x-x = 0 → 9x = 0 → x = 0
And since we know 0.999… = 1, that means that …999 = -1, because …999 + 0.999… = x = 0.
And for those in CompEng and CompSci, …999 is just the 10's complement form of -1.
Another things is …999 + 1 = …000 = 0
Of course, this …999 = -1 doesn't hold in the reals since an infinite string of 9's is just infinity.
fuck you
Why?
is this comic accurate?
Yup. Euler's identity is hella fine.
...
You obviusly wrong. And I sick of people try convincing everyone in this prank.
dats pretty randums lel XDDDDDDDDDDDDDDDD
