I go from 1-5 on my left hand, starting with pointer and ending with thumb, but from 6-10 on my right hand, starting with thumb and ending with pinkie.
I start with the right pinky and fold the other four down when I reach five and extend my thumb. Then to count six, I extend that same pinky without folding down the thumb, add in the other three fingers in the same order to get to nine, and start the same system to count tens on my left hand.
I think I started doing it in college, when I had to count people in a class and frequently forgot which multiple of ten I was on. I just kept doing it, and now it’s more or less automatic. I have to explain it to people every now and then, but they mostly just don’t want to ask what the hell I’m doing.

Last year sometime, two employees in my company were standing in my office. Employee “A” is missing his right thumb. Employee “B” has a “twin thumb” on his right hand. I have the standard number of thumbs, one on each hand.
SO, one COULD say that, ON THE AVERAGE, everyone in my office had two thumbs!
I had to share that vaguely-oogy story when I saw a thread about fingers.

I’m about the same as racinchikki. The only difference being I do the 1-5 on my right hand, starting with pointer and ending with thumb, but the 6-10 on my left hand, starting with the thumb and ending with the pinkie. I figure as long as I’m not stomping a hoof and whinnying, I’m not that strange.
I was in third grade when chisenbop (a korean teachnique of finger-math) was briefly in vogue and we were taught that and I can’t bring myself to do anything else (from pinky to thumb for 5, thumb +pinky=6 (all consecutive fingers put down stay down until 5 or 10 is hit, so you can look at your hand and see where you ended up), and when you get to your thumb again the left pinky goes down for 10-- 10s are counted in the same way on the left hand)
Since I probably have a pen in my right hand when doing math without a calculator, I’ll count on my left hand and go pinkie to thumb in an “inward” fashion.
Of course if I have to count to eleven I unzip my pants.
