comment Why Not Define $0/0$ To Be $0$?
you "proved" by multiplying all by $0$. $0$ is a number.

what you are doing is impossible, it is irrelevant to whether 0/0 is number or not.

comment In dual numbers, what number is represented by the following matrix?
what reasoning do you mean?

comment Why Not Define $0/0$ To Be $0$?
You wrote: $$\frac{1}{1}-\frac{0}{0}=\frac{1\cdot 0-0\cdot 1}{0\cdot 1}$$ - no, you cannot do this, you are multiplying thenomenator and numerator by zero, this does not prove anything (similar way you can prove that 2=1, so 2 is not a number)

comment In dual numbers, what number is represented by the following matrix?
I have already found it is sometimes denoted $\epsilon'$. Also it seems, it is $i+\epsilon$?

It is dual because p as defined here is 0 en.wikipedia.org/wiki/…

comment In dual numbers, what number is represented by the following matrix?
If it were $\epsilon$, then subtracted by $\epsilon$ it would give 0. But it does not. Note that not only $\epsilon$ gives $0$ squared (for instance, $-\epsilon$).

@Taladris its p-factor is 0 so it is clear dual.
