I found this on Geekologie.com and found it interesting along with your other articles. I thought this would be a great way to communicate in code at school (Yes I'm still into those things.. as well as the prospect of passing around 'innocent' equations in maths classes) but I still haven't figured out how to insert the equation into graph mode as I keep getting syntax errors xD, not to mention the gigantic equations. Do you know how to put this into a graphics calculator so it shows the words? (Model is CASIO Fx9860G series, sorry if this is a stupid question, you can download the emulators from internet sites)
Thanks in advance (I did japanese at school too ;D )

Hey Random,
Hard to get these into an actual grapher. Like you said theyre just too complicated. They use absolute value sign, which a lot of graphers dont like. (Of course, |x| is the same as sqrt(x^2)...)
You *can* kind of "read" the equation though. An (x-5) factor means a vertical line at x=5. A (y-x-1) factor means the line y=x+1. A ((y-x-1)^2+|x-2|+|x-3|-1) factor means the line y=x+1 but only from x=2 to x=3. (See http://www.xamuel.com/line-segment-equation/)
