My boyfriend is tutoring some kids in chemistry and trigonometry and would like to be able to do it electronically. Is it possible to do chemistry and trig simultaneously and remotely. We have figured out how to do a chem or math problem on our wacom but could someone do the same problem at the same time simultaneously on their wacom if they have one. We've used windows journal but I can't figure out how to share the screen/page and share the changes as their made in the solution to the problem? - sheila
