I'm stuck at 18, which looks to me like binary. I don't know binary.

Alex · 10-25-2006, 07:26 PM

Binary is easy, just iterate it once.

0 = 0
1 = 1
2 = 10
3 = 11
4 = 100
5 = 101
6 = 110
7 = 111
8 = 1000

and so on.

In base 10 the right most columns are 1s, with up to nine of them. The second are 10s with up to nine of them. So 89 is 8 tens, and 9 ones. Each column to the left multiplies the previous one by 10.

In binary, each column to the left multiplies the previous by 2. So the rightmost column are 1s (up to 1 of them), the next are 2s (up to 1 one of them), the next are 4s (up to 1 of them) and so one.

Next time you hit something like that just remember that Americans don't know the Presidents either, and that it's probably either Lincoln or Washington, and in this case it couldn't be Washington because he was the first.

But if you don't know presidents, then how did you know Buchanan was a president?

Adams tends to be a good answer as well. The name always rings a bell, but no one can ever recall what he did. Plus, there were mutiple of them, so if they say you are wrong on something, you can just say you meant the OTHER Adams.

It figures a typo would stall me.
