What happens when division by zero is attempted?

Answer 1

Division is glorified subtraction (like multiplication is glorified addition). Ex. 20/5= 20-5=15; 15-5=10; 10-5=5; 5-5=0 thus 20/5=4

Now, let's apply this to zero

20/0= 20-0=20; 20-0=20... etc.

so therefore this would leave one to believe that the answer is infinity; however, when you learn limits you learn that when 20/x approaches zero from the positive direction it is infinity, but from the negative it is negative infinity. This means there is no answer. Being that infinity is an expression and not a number nothing can actually equal it... Thus 20/0 could equal blue. But for sake of argument let's say infinity was a number so 1/0=∞ and 2/0=∞ so that means 1/0=2/0 which means 1=2 which is obviously not true.
