Of course, it all depends on if it was put there by Gen, or put there by SHAFT. A lot of things Shaft does just to spice up the visuals(for instance actually making Kyube look creepy), and I have to wonder whether Gen was actually thinking mathematics.
On the other end, that level of math for 14 year olds, does imply that if anything, they should be smarter than the average person, which puts their actions, thoughts, and decisions into more of a strange light.
