>>11265034A) Division is the inverse function of multiplication.
B) Multiplication is iterated addition e.g. 5 * 3 is 5 added to itself 3 times.
Given A and B, I now ask you, OP:
How many times do you need add one to itself in order to reach an answer of 0?
Note that it is 100% possible there is no amount of adding 1 to itself that will ever result in the answer of 0, in which case 1/0 would be undefined.
