Nuuu don't let the math thread die!
Yeah, let's not. The last time that happened, it took hundreds of years to come back.

(well I didn't mean odd odd, I meant odd... you get my drift?) other systems were huge like base 60!
I think either you mean 'strange', 'unusual', 'non-standard;, 'bespoke', or 'unique' for the numbering systems they use. When there is something people use a lot, eventually people will move to the one that is easiest to use.
Remember I said that three of the greatest inventions of mankind were standardized numbers, the zero, and the decimal point?
This is, I think, the reason that decimal arithmetic, with the zero, positional notation (99 means 9x10¹ + 9 (or 9x10⁰)), and the decimal point, became the defacto numbering system in business, science, technology and simple arithmetic, because it is trivial for even children to learn. Had people had 12 fingers, we would have developed a base-12 numbering system (let's call it duodec) and arithmetic would use powers of 12, and fractional numbers would be expressed using the duodec point.
In computers, numbers using base 2, just 0 and 1, are in binary and are expressed as powers of 2, and fractions use a binary point.
Where computers use numbers using base 8, digits 0 through 7, they are in octal, are expressed as powers of 8, and fractions use an octal point.
Where we have numeric bases larger than 10, a general consensus is, for normal arithmetic, to use the standard roman character set, A-Z without regard to case, so that Using the standard alphabet with case-insensitive letters, 11 decimal has value 1011₂, 13₈, 11₁₀, 10₁₁, or 'b' or 'B' for every base above 11.
Where computer use numbers using base 16, digits 0 1 2 3 4 5 6 7 8 9 A B C D E F, they are in hexadecimal, are expressed as powers of 16, and fractions use a hexadecimal point.
To indicate the period being used to separate the whole number from a fraction, regardless of which numeric base it is, we have a name for it, the
radix point.
This means you can go up to base 37, using 0-9, A-Z, then 10₃₇ for 37₁₀.
of it hooked up to the tv 
. I had a warrent and when I was 19 it caught up to me. They put me in jail for 12 months for Illegal Cable! This was just after there was a law passed that foster parents could adopt 1 year and 1 day after the child was put I'm their custody. I had 1 day to get a 3 bedroom apartment. It had to be 3 bedrooms because one of my children was a boy. Welfare would not help me UNTIL I had the children in my custody. So I lost my 3 children over 1 months rent. After that I only had Noel.
