The group I last gamed with had guys with degrees in History, English, Accounting, Computer Science, and a couple that didn't have degrees. In terms of the best mathematics ability, it was probably me (Computer Science), the History major, the guys without degrees, the English major, and finally the Accounting degree.
The accountant blamed the fact that he was always using a calculator for him not being able to do simple arithmetic . . . or even to count the pips on his dice correctly.
