Figure out your strategy for writing your math questions or posting responses to others.
Here we have a real problem, but don't worry, there are ways we can make it easier. I recommend one of the following solutions:
1. Take a photo of what you've written on a piece of paper with your computer, tablet, phone or whatever. Now use the image tool in the P2PU rich edit box - 
- to include it in your post. You have to first choose "upload" in the dialog box's tabs.
2. Use a tablet drawing program or some other combination of hardware/software to write your mathematics digitally and save the results as a photo. Now upload the image as in the first option above.
3. Just use a webcam. This might be a good option if we use Skype or a chat program to have a synchronous meeting of interested participants.
Any other ideas?
