When I was at school, they told us that we had to learn to add and multiply because we could only count to ten on our fingers.
The instant response was that we could get to twenty using our toes (if we wore sandals all year round).
It didn't take much longer to figure out that 30 was achievable by counting 'ones' on one hand and 'fives' on the other (25 + 5).
But (despite my otherwise-solid geek credentials) it took my husband to point out that, actually, it's perfectly easy to count to 1023 on two hands... in binary :)
