Adding fractions, one step per denominator

I didn't give GC enough credit. Fractions with different denominators can be added directly via "drag algebra" as follows:

Pull over to the right as far as possible, and you'll get the following. Note that GC automatically puts in the parentheses and places the terms you're dragging in the denominator of the new factor:

Finally, Simplify the whole fraction:

Check results by graphing the initial and final result. You could also graph each step along the way, to be safe:

Hi Graphing Calc Users,

I've not used this software before but I noticed on the tour page
there is "drag algebra". I was wondering if you've taken that concept
any further? For example doing calculus/algebra manipulations with
clicks and drags, etc.

For example something like the attached image..

Can that be done with "Graphing Calculator"?

Thanks,
John
