While math is one of my deepest passions, I cannot help but disagree that the ten most positively influential events in human history are all developments in mathematics :)

Without math you wouldn't know there were 10 in the list!

Quick, what is the highest number you can count to using only your fingers (and thumbs if you want to be pedantic)?

1023! Binary - but you need some super flexible fingers :)

You can use your hands to easily count up to 144 in base-12 (or 120 depending on how you look at it ^__^).

Edit: For continuity, I originally posted 60.

I've won a TON of money in bars (and not beaten up once!) with this question.

You can count to 144 easily using your hands - thus the importance of "gross" in every society.

There are several ways to do this sort of counting. I like this guys, but that is not actually how it is done in most places.

Use your power wisely, always for good, never for evil.

what if you count the meta-carpals that would give you base 20 and would let you count to 400. edit: I can not believe I said tarsals [embarrassed]

Lol, I edited that right as you were posting.
