What is infinity divided by infinity? - Mathematics Stack Exchange
Aug 11, 2012 · I know that $\infty/\infty$ is not generally defined. However, if we have 2 equal infinities divided by each other, would it be 1? if we have an infinity divided by another half-as-big infinity, for
soft question - Why is $\infty \cdot 0$ not clearly equal to $0 ...
Mar 25, 2011 · (i.e add 0 0 to 0 0 as many times as you like, result is 0 0) So I thought an infinite number of 0 0 's cannot be anything but 0 0? But someone claims different but couldn't offer a reasonable …
One divided by Infinity? - Mathematics Stack Exchange
Similarly, the reals and the complex numbers each exclude infinity, so arithmetic isn't defined for it. You can extend those sets to include infinity - but then you have to extend the definition of the arithmetic …
What is imaginary infinity, $i\lim\limits_ {x \to \infty} x = i\infty$?
May 14, 2017 · The infinity can somehow branch in a peculiar way, but I will not go any deeper here. This is just to show that you can consider far more exotic infinities if you want to. Let us then turn to …

For infinity, that doesn't work; under any reasonable interpretation, $1+\infty=2+\infty$, but $1\ne2$. So while for some purposes it is useful to treat infinity as if it were a number, it is important to remember …
infinity - What is $\frac {1} {\infty}$? - Mathematics Stack Exchange
May 28, 2017 · Note that stating the reverse is more delicate, since we use to give a sign to infinity. Both $\lim\limits_ {x\to+\infty} \frac 1x=\lim\limits_ {x\to-\infty}\frac 1x=0$ but we cannot conclude $\frac …
