Fractions n' junk

It means that the fraction is undefined since we cannot divide by 0

Here's why

6 / 2  = 3       means that the  result, (3),  times the denominator, (2),  returns the numerator, ( 6 )

But what about  :

6 / 0   =  b  ???  

This would mean that b * 0  = 6  ......but this is impossible since anything times 0 should return 0.....!!!!

That's why the calculator goes into convulsions.....!!!!!
