lol, I know it is a pointless exercise, I just want people to get the math involved without spelling anything out. That does not make them better programmers. If you take a + 4 mod 4 it is going to be equal to a mod 4. duh!
It becomes useful as Numsgil exposed math to conditions a while back, you can for example get away with
cond
*.robage *.robage1 32000 mult add
32000 777 add >
start
...
stop
I am really going to sleep now
