Why do we group numbers by 10
Why not any other arbitrary count like 4?
as in
1, 2, 3, 10, 11, 12, 13, 20, 21, 22, 23, 30, 31, 32 33, 100, etc?

>> No.9396303

because we have 10 fingers probably

Not everyone uses base 10 and no one is forcing you to use it either.

>> No.9396322

>>9396296
Best base would be base 30, would correspond roughly with the letters of the alphabet, you also have about 30 joints on both hands. Also divisible by 2,3,5.

Base 30 is just too many symbols.
Hexadecimal is useful for computing, but that's about it.
Best system to use in day to day stuff would be dozenal.

Best base is 12. Far more factors than 10 (or 30): 1,2,3,4,6 &12. Base 12 is much more efficient than base 10 for everyday human computation.

You can even count to 143 on your hands using the 3 segments of each of your four fingers.

this

>> No.9397876

there have been counting systems with bases like 5 or 20. it seems to have come from the number of fingers or (toes) that ppl have

>> No.9397895

It actually has to do with the complete superiority of the number 9. Trust me. This number in base 10 is not comparable to any of its other forms.

A close second is so the first 144 digits of π add up to 666. We have to keep that message going until you apes are ready to evolve.

If you've ever watched The Simpsons then you'll have noticed that they all have 4 fingers per hand for a total of 8 fingers and yet despite that they still use base 10. In the few episodes where God appears, he has 5 fingers per hand for 10 fingers, showing why The Simpsons use base 10.
Hence, we group things by 10s because we have 10 fingers. We could also do it by 12 or 24 because we have 12 knuckles per hand (using the thumb to count them out), which is how the Babylonians did it.

By the way, we do use other bases
For example, computers use base-2 (0 and 1)
HTML colour coding is in base-16 (or hex)

Etc

There's a bunch of applications for a lot of bases

4 is useful for some things.
Binary seems like the natural desu.

>> No.9403084

cuz we have 10 fingers. But we use binary too (base 2) in some cases regarding computers because computers use binary because it only requires 2 modes for bits to be able to describe things (on and off).

>> No.9403715

>>9396303
Yeah.

Come to think of this, this is the only basis we have to be on base 10. Incredible.

I mean Base 12 is clearly the patrician's choice
> divisible evenly by 1, 2, 3, 4, 6, and 12
> makes splitting things 3 or 4 or 6 ways easy
But it may take a serious near-earth hypergate accident for us to change our ways.

Eskimos used Base 6 by the way, they would count up to 5 on one hand and when they reached 6 they would just add one to the other hand and reset the singles digit hand
> they could count to 35 using two hands

>>9396393
I disagree about the symbols chosen for ten and eleven but I agree with base12 completely. I think we should use symbols from other languages that represented those numbers as a single digit.

>> No.9404000

>>9403915
>>9396393
I'm fine with it being 0123456789X, but the symbol for eleven is retarded. Some weird upside down 3? Just use E instead. My keyboard has no upside down 3 and I'm not typing ctrl-shift-u every time I want to type a number.

You mean the first 144 decimals. The first 144 digits adds up to 669.
