> Dude was a math grad student. I narrowly restrained myself from saying ... Do not show restraint, and neither will I. For I am a mathematician, not a fucking calculator. But once, early in undergrad, I was capable of multiplying 4-digit numbers rather quickly. But tallying never seemed useful except while grading exams -- during which my brain populates a lookup table over the course of an hour, and then I can tally small sums without hesitation. But after that day of grading, the lookup table is flushed for more important uses of short term memory.
