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

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.

It's not fair - I don't know the order of all the USA Presidents..... :rolleyes:

It figures a typo would stall me.

I got to the end. Woody.

Got it! Finally.

The 16th is apt to give you a haircut...

and tell you YOU MUST LIIIIIIIVE!

IN SUPER STEREOPHONIC SOUND!!

I now know several different Latin spellings for 17 and two different Greek spellings for a 21-sided polygon. Where is BinkelBop? I'm sending him a bill for that shyt.
