Is there anything about the decimal number system that conveys any advantages over any other number system?
So is it any more likely that some other alien race would use base-10 numbers in everyday life or are they just as likely to use say... base-8 or 12 (8 fingers and no thumbs, or 12 joints in the fingers)? base-3? 16? 29? 100? Or is there some useful property in base-10 numbers beyond us being able to count with our fingers?
