>>14285162We have 10 fingers, this is why we use base 10, base 10 however is less divisible then 12, 1 2 3 4 and 6 all go into 12 however only 1 2 and 5 can go into 10. 10 has a repeating decibel when divided by 3. 12 is superior for this reason, as a base 12 whole can be divided into thirds. ie base 10 = 33.333333% reoccuring. base 12 = 34%. base 12 is easier to work with but the larger the base the worse it is because we have to remember more digits, such as 1 2 3 4 5 6 7 8 9 a b 10. We already use base 16 for colours which is why rgb goes up to 255 and is representable by values anywhere between 00 and ff. Using letters in your number system is of course stupid, so what would the 2 extra digits look like?
