Online study and draw/explain program?

[christian0710]

Hi,

Is there a software that allows a group of people to be online together and explain stuff like physics and mathematics which includes shared screen and perhaps a shared drawing utility or math unitedly?

What would be some of the best options?

teamviewer.com has been suggested here before, but it's pretty expensive.

Thank you, I'll look into that, if it's the best option.
