I wrote a system that could display a process of simplification of a
math formula as an animation/cartoon. It is targeted towards children.
Example is at
http://www.algebra.com/services/rendering/regression.mpl
Check out second to last image, it is a cartoon of how to simplify
(x^2-y^2)/(x-2)/(x-y)
You can see it directly at

The idea is that it will be used for my free tutoring system. Any
tutor explaining a math problem or writing a lesson, could easily
write a simple expression that would draw a "math cartoon". It is
already
working, actually.
In the case of the above cartoon, it could be defined as
cartoon(
(x^2-y^2)/(x+2)/(x+y),
(x+y)*(x-y)/(x+2)/(x+y),
highlight((x+y))*(x-y)/(x+2)/highlight((x+y)),
cross((x+y))*(x-y)/(x+2)/cross((x+y)),
highlight( (x-y)/(x+2) )
)
As I said, it already works. Some feedback will be appreciated. I am
chromatographically challenged and will appreciate feedback on color
selection etc.
This will, eventually, be a part of the simplifier that I am writing,
but right now it will be used by humans solving problems manually and
wanting their solution to be fun and good looking.
thanks

Re: My new mathematical cartoons (related to simplification)
I was redirected to algebra.com from tinyurl. It goes by too fast for my
old eyes. I would suggest the original problem and an explanation of
factoring, and the next step and an explanation of further factoring and
the next step... Probably with a next button to trigger the next step.
Fascinating though. It's certainly a proof of concept that's worth
further development.
