[stylist] Comma rules

[Eve Sanchez]

So Chris, does that mean that the temperature was the same each day
through out May? There is no other explanation for adding up 31
numbers and dividing by 31 to get the highest. 80 X 31 divided bt 31 =
80, but 80X 30 plus 82 divided by 31= 80.06 which is not the highest
temperture. Oh, and thanks for the vocab lesson. I always get that
stuff mixed up, but I do know my math regardless. ;) Eve
