Oh no! Marin Mersenne can’t seem to find his homeroom!
[Solution: Although there are a lot of great mathematicians named in this post, the only range which matters is Klein to Lagrange, which includes M for Mersenne. However, the room numbers do not seem to make sense, and it turns out that you need to find the congruent room number in modulo 2147483647. This leads to Mr. Davis’s room, room 314.]
Hint 1: Make sure to dot your i’s and sign your numbers.
Hint 2: 1+12=1. Well, actually, in this school it’s still 13. Too bad! Try again!
Hint 3: Remember, school ends at 2147483654:2147483677 o’clock P.M.
