I downloaded the Mathardy For seventh grade math And unfortunately I do not have Microsoft PowerPoint.  I got the viewer from Microsoft and was able to open the file but I get none of the hyperlinking features that I trust are supposed to be there. Does anyone have a suggestion beyond getting a copy of Microsoft for me?

This is a feature that once upon a time was built in to Microsoft and one could create a game like this very handily. Maybe it's not even there anymore.
