A related question. Is there any current support for something like an "equationresponse"?
For example, an answer like
"x > 7+y"
I realize this could be put together using combination of response types (like a drop down for the ">" sign and a formula reponse for the RHS).
Will this be something that will be possible with <mathresponse> or the symbolic algebra?
Best,
Jay

*Hi,
With one of the upcoming versions, you will also be able to use
<mathresponse>:
http://www.lon-capa.org/mathresponse.html
- note the sample problem given there actually has infinitely many
correct solutions.
But, again, that's not yet in the current production version, just a
little teaser.
