ok, I am here to show you how i = -1.
first a wiki article so you know what i is.
so 1^2=-i, right, so then -i=1. then you invert it beacause if x=y then -x=-y, so in format, -- i=i,and then --i=-1! so i=-1.

edit: I'm wrong. just look well at the wiki article.

if yuo add the string "1" with the string "1" you get 11, and 11 in binary is 3.

so many people say you cant save music in fl demo version but it is simple
files>export>mp3 and then it will bring up the save window.
