Math is one where the more time gaps you have in terms of utilizing the skills needed for a particular type of problem solving, the harder it will be, not only to get into the swing of things, but to rebuild understanding (on avg, for most). As well, math's a great exercise in brushing up on skills for the game of logic. Math problems are like a game to me, in many ways. A puzzle, a riddle...
Of the three broad branches, Calc, Algebra & Geo, Stats/Finite...my favourite is Calc, learning the limits of math and all.
My area of expertise is one where I'm neck-deep in Statistics. It's a love/hate. Hate because when I'm 'forced' to delve into a topic, my mind automatically counters with a conditioning of 'distaste'. And, higher-level stats for multi-factor complex analysis and such, where controversies, debates are rife...well, kinda mind-numbing. If you've ever been privy to seeing biostatisticians duke it out, you'll understand. And, quite a few of them have thick (THICK) accents.
Piss-on,
Piss-on....does he wanna be pissed ON or piss ON someone? POISSON DISTRIBUTION! Ah!
I used to love it when I was a kid, and would do math competitions as extra-curricular activity (part of the

club! yup!). I won provincewide too,
CEMC - Mathematics and Computing Contests
Now, when I'm bored, I sometimes do some of these math competitions/exams, just for the hell of it, and to get a different perspective of seeing the exams, versus how I perceived them when I was a kid....as they're pretty easy level for adults. So it's fun.
YEAHHH MATH!
