Please, can you give a source (book or so) where I can find this explanation? I have checked over several books and no book speaks something about the mean of negative and positive numbers.

Thank you. Is there any video on weighted average where the weights are positive and negative?

Question: what materials did you use to write? Is it really just a glass screen? Surely it's on a separate board and green screened in? What markers are used for something like that? thanks
