You can divide by zero. If zero is one divided
by infinity where infinity = A then one divided
by infinity = 1/A. Then take a natural number
say one. Then 1/(1/A) = infinity = A. To reverse
the operation mulitiply A*(1/A) = 1. Einstien
didn't care what the numerator is as long as it
is a real number not = to zero or the infintesimal
because infinity is infinity. The infintesimal is
one divided by infinity and that is a special case
of zero.
If zero is nothing then a number divided by zero
equals the numerator.
if zero is a minimized binary number and it is one digit
long and is one unit then it takes up the same amount of
space as one and division by zero equals the numerator because zero is one not zero, logically according to Spock.
Also, sometimes division by zero is not reasonable
because a number divided by zero just doesn't have a reverse procedure.
