Hello. I'm a former engineering and math student, and a lover of numbers.
I seem to almost always be doing mental arithmetic, such as multiplying the two two-digit numbers of car plates, factorizing big numbers, and trying to find patterns to help me memorize irrational numbers. I love e, pi and the infinity of primes. Also a fan of Numberphile.
