Re: [GraphingCalcUsers] Adding fractions, one step per denominator

John,

Sounds interesting, and I'd like to see the demo, but I haven't been able to view either file so far.

I get this for the .mpg file

and this

for the .wmv file. I'm using an iMac with OS 10.4.10

Very nice!

I like how the end result look like out of a textbook.

Graphing Calc looks to be the only program out there that tries to do

draggable math.

By the way in I've written a program that does this sort of thing but

with the ability to do arbitrarily complicated math/calculus, with the

mouse, as one would do by hand.

or

http://peberdy.ca/jp/projects/files/demo1.mpg

So far it supports general high school math to 2nd year university

calculus (and common identities). It also outputs the result in PDF or

the typesetting language known as LaTeX.

Any comments welcome.
