Math via Skype on a Mac? I find myself needing to explain math via Skype (to nephews, nieces in high-school or college, etc.) with increasing frequency, enough so that the clumsy approach of holding a pad of paper up to the camera is beginning to get irksome.

Typing out the math into the interface's text field, or anywhere else, I find even more irksome.

I would like to communicate the math, in real time, both by voice and by writing, sketching, etc.  Preferably I'd also like to be able to see the person I'm showing the math to.  With Skype I get the real-time voice and image communication.  I just need a way to add a handwritten channel somehow.

Can someone recommend a way to do it on a Mac?
Did you try the screen share?

It does require you typing, but not in the Skype field.

You could use excel or word to type, and then share your screen with others.
