Re: Interactive computer algebra: with clicks and drags


I remember Milo. And Theorist.
Clicks and drags to do symbolic algebra.
They were great!


Oh I see its far from a new idea. Still I think my interface is
cleaner and more intuitive! :)

Something I remember from long ago.

Somewhere on my work*** is
x = a + b
Somewhere else is
y = x^2 + 2*x + 4
Take the mouse, drag that first equation onto the second, and see:
y = (a+b)^2 + 2*(a+b) + 4

Another one. I have equation
x = a + b
Grab the a and drag it to the left margin to get:
a = x - b
