[LON-CAPA-users] mulitple correct answers in a numerical

[GARRETT, DONNELL MAZON]

Hi

Let's say in a numerical response I would like to accept both answers of
-90 and 90 degrees.

How do I do this?

I looked in the FAQ and they have how to accept this type of answer in a
string response type question, but I tried something similar for
numerical response and it does not work.

Thanks

Donnell
