4 mathematicians are invited to solve an enigma. Once there, they're locked in a mechanically shrinking room and given 1 minute to solve each puzzle via cellphone while also figuring out why they're there.
When Galois is showing off to the young women about how every even number is the sum of 2 prime numbers, he chooses the number on the license plate of a nearby random car. But when he picks up Hilbert, he is driving this car, so of course he already knew the "solution" to this large number on his own car.
Do you know what prime numbers are? Because if you don't, you should just leave now.
The riddle about three daughters's ages has multiple solutions (assuming that age differential of one year is allowed and that piano lessons can start early in life): 4-3-3 and 6-3-2 in addition to the stated 9-2-2.
During the end credits, all accents are added later than the text appears. The character Hilbert is seen doing that continuously during the movie.
