A hopefully small issue in a counting system

I'm making a race that counts in base 7 but I'm having trouble with the worldbuilding for why that is. Is their a reason that a creature evolved to the point of being a sentient humanoid would be asymmetric as one would probably be to develop base 7? This race doesn't really belong to a homebrewed world yet so there is pretty much free reign on what the cause is.

Religious reasons maybe?
But really, having your "native" base be prime number is kind of bullshit. Unless you are a computer.

So you thought "oh yeah having a different number system would be neat!" and didn't otherwise think of why that would develop in the first place?

Is there a reason they wouldn't?

They've got eight eyes and no real digits to count on. They don't use base eight because closing all your eyes when you count is dumb.

3 fingers on each hand and they learn to count with their dick too.

Couldn't they have two hands with seven fingers each and have arbitrarily decided the number of fingers on one hand rather than on both hands was the one to base their number system on?

Depending on how you look at it humans have 5 extremities (arms, legs head), so it wouldn't be that weird to have a creature with 7

Why didn't I think about fractions... Okay, great point on the prime number thing. Of course there was a reason it hasn't developed before. This whole thing is a moot point know really

If memory serves me right, the ancient greeks (and older) used base 12

>2 fingers on each hand and they learn to count with their dicks too.

I came here to say this. Do it OP.

Also, in case it's not obvious, this would mean they count with a ones hand and a sevens hand. If humans did the same, we could count up to 30 on our fingers.

Seven fingers. Left hand is multiples of seven. Count up to 49!

If you count in base 2 on your fingers you can count really high

FIDDLER CRAB PEOPLE!
Five fingers on left hand, right hand is a BIG MEATY CLAW!

They natively count to seven.

They are quadrupedal with four (or six, on males) legs (the males have the extra two to hold on to females, also: manspread on subways.) Because their legs are irregular in number, they count on their fingers, and the CLAW.

You can count to 56, I think, if you go by your current number being (Left Hand)x7+(Right Hand).

Technically if they had two hands with seven fingers each, they could count to 63 in base 8 since zero is a digit. But I'm not sure that would be intuitive for a humanoid race.

Humans are asymmetric too. Our limbs and chests often vary in size. Then our internal arrangement is obviously asymmetric.

3 fingers per hand + prehensile tail

3 fingers on their hand, and count their head/vision as the seventh, and they worship things in 7ths because it symbolizes their sense of self.

am I the only person who does this?

just spitballing here, but I think it's because symmetry allows for more redundancy.

Base 10 is common amongst humans but by no means universal.

Technically, in the two seven-fingered hands idea they WOULD be counting in base 8.
fingers on hands - base10 number
00
01 - 1
02 - 2
etc
07 - 7
10 - 8
11 - 9
This is base 8 count.

Base10 fingercounting is just an out of line with the way scientific maths function. Technically it would be base 11 if we used all our ten fingers for one digit. But we tried to use them for both.


2x7 fingered creatures may naturally arrive at a more properly scientific fingercount

Well, humans have used base 10 and base 12/13 counting systems.

Base 7 could work for a 6 fingered race that treats one hand as a ones had and a second hand as a tens hand, similar to how we can count up to a gross (144) using one of our hands as a singles hand and the other as a dozens hand.

To count in base 13 on the human hand use each of the 3 sections on each of your 4 fingers on one hands (use your thumb as a marker). Your other hand is used to track completed dozens(base 12) or mark "10s" (base 13).

Primary hand.
Pinkie has 1, 2, 3
Ring has 4, 5, 6
Middle has 7, 8, 9
Index has 10, 11, 12

Secondary hand (base 12)
Pinkie 12, 24, 36
Ring 48, 60, 72
Middle 84, 96, 108
Index 120, 132, 144

Secondary hand (base 13)
Pinkie 13, 26, 39
Ring 52, 65, 78
Middle 91, 104, 117
Index 130, 143, 156

Not every human civilisation or culture counts in base 10
The whole "counting on your fingers" thing, is what we use, however there are tribes and shit that count using base 32 and shit like that.

This will be a useful thing to watch for working out base systems for a race
(also mono-culture races a shit, not every member of the species will use the same base etc)

OK, so tell us how/why the base13 system developed and we'll help you more with base7.

Same reason americunts use inches and feet.
Just cus

I do it sometimes. When I was in highschool, a friend demonstrated it after I demonstrated counting to 110 using two hands. At least I think that's how it happened; it's been a while, much too long a while.

This gif upsets me, and I don't understand why. What is happening here? Why? How?

This doesn't sound very comfortable. Like, try to bend only pinkie and middle finger, while keeping every other finger straight.

It probably gets easier with practice.

Just like your mother.

I am not the OP, but thanks, this is great video.

Or a Tail. You could just give them a Tail and they use that while counting

You mean like how we have an even number of fingers on a hand?

Oh wait.

Just make it base 17 and give them 7 fingers on each hand or something.

Or just give them 3, but for cultural reasons they also count the head, so 7.

You are massively overthinking trying to make this "make sense"

It's not a case of 10 being super logical so of course we use it, it's a case of us using 10, so of course it seems super logical when everything is built on it.

Way back in the day (as in early to mid bronze age) a few mid east cultures used base 6.

What the fuck does symmetry have to do with having an odd or even number of digits?
