Ok I am in grade 9 and I am maybe too young for this.



But I thought about this, why dividing by 0 is impossible.



Dividing by 0 is possible would mean 1/0 is possible, which would mean 0 has a multiplaction inverse.



So if we multiplicate a number by 0 then by 1/0 we get the same number.



But thats impossible because all numbers multiplicated by 0 gives 0 therfore we cant have an inverse for 0 that gives us the initial number and thus division by 0 is impossible



Is this right?

That's the most basic reason that division by $0$ is usually considered to be a Bad Thing, yes. Because if we did allow dividing by $0$, we would have to give up at least of one of the following things (these are usually considered Very Nice):



  • What $1$ means ($1cdot a = a$ for any $a$)

  • What $0$ means ($0 cdot a = 0$ for any $a$)

  • What division means ($frac ab = c$ means $a = ccdot b$)

    You might be interested in, for example, Wheel Theory, where division by zero is defined.
