Don't worry PoK seems just like a load of gibberish.
Basically
A=-1+1 (A=0)
B=1+1 (B=2)
Distance=B-0-A (Distance - a variable never mentioned before or after - is 2-0 so it's 2)
-Zero=-Inc A or B (Random rubbish for no real reason)
=1+1-0+1-1 (over a few lines, he figures out that 2+0=0. well played)
=2-0+0
=2-(-1) (now let's introduce some random numbers for no real reason)
=2+1
=3 (now some random irrelevant primary school maths)
this one restricts itself to less eccentric mistakes though...
-10=a#
a#=0.08 (I think these lines were supposed to be the other way around. You can assign data to a number like you would a variable, but you would have to declare a# first. Also wouldn't it just take -10 as an integer of a#?)
Opr#=10.0+(-10)
Print "Result : ";Opr (this is pretty irrelevant as there isn't an Opr yet declared - before that you had Opr#)
