I misread your average. You are correct. But the point stands: it's quite
possible to have positive numbers and negative numbers in an average.

Actually, yes I am assuming that. In practical terms, it wouldn't make
sense to average both positive and negative numbers and omit zero.

Hi Chip,

Where would zero come into the following?

1st Month: $100 loss
2nd Month: $100 loss
3rd Month: $500 profit

3 monthly average profit would be $100 profit.
