I am a complete amateur, but I've attempted to define division by zero. This it's usually classified as undefined. After all, if 1/0 = b, where b is some non-zero number, then b times 0 would have to equal 1, and there exists no real number that, when multiplied by zero, equals 1.
Therefore, it was evident that my definition would necessitate the creation of a new kind of number. This number, which I call Z, is defined as Z=1/0. Z is thus the reciprocal of 0.
Playing with this new number for awhile less me to discover that 2/0=2Z, and so on where n/0=nZ. This leads to a whole set of numbers, Z numbers, similar to imaginary numbers. After all, imaginary numbers were created to define something that was formerly undefined, namely, a number whose square was -1. This leads to the whole set of imaginary / complex numbers.
Already I've discovered interesting facts about this number Z, such as the square of Z is equal to Z, since 1/0 times 1/0 equals 1/0.
My question is, is there some way in which my new set of numbers to define division by zero falls apart under closer scrutiny? I have yet to discover one, but I'm very new to mathematical exploration.
I apologize for not being familiar with the Math font used to write equations.

4$\begingroup$ I think you quickly run into problems with your definition if you want any of the standard rules of arithmetic to apply. For example, if $Z^2 = Z$ as you say, then we should also have $Z^2 \times 0^2 = Z \times 0^2 = (Z \times 0) \times 0 = 1 \times 0 = 0$, but on the other hand $Z^2 \times 0^2 = (Z \times 0)^2 = 1^2 = 1$. $\endgroup$– Gregory J.

3$\begingroup$ This doesn't seem any different from the symbol $\infty$ any entails the same difficulties. What is $Z-Z?$ or $Z/Z?$ $\endgroup$– saulspatzJul 30, 2018 at 4:15

2$\begingroup$ @GregoryJ.Puleo Since $0=-0$ and pretending basic algebra stands $\,(-1)/0=1/(-0)=1/0=Z\,$. $\endgroup$– dxivJul 30, 2018 at 4:25

3$\begingroup$ You would lose associativity since $2 = 0\times(2\times Z) \ne (0\times 2)\times Z = 1$. $\endgroup$– user856Jul 30, 2018 at 4:30
