XXX: You know, this is what I understood...
We have been fooled all our lives and not agreed.
YYY :?
Do you remember how it was at school?
xxx: First they said that the smaller more can not be deducted - and then they talked about negative numbers
xxx: Then they said that 5 by 2 is not divided... and then they talked about fractional numbers
xxx: Then they said that the root of a negative number is not taken - only to tell later about complex numbers
YYY :D
xxx: I think... Maybe I went away in vain in the second class – maybe I would be allowed to divide by zero?
