        There are 12 sections on your fingers (excluding your thumb) you then use your thumb to count to 12 on one hand.

        Two hands can allow you to count to 24. Which is way higher than 10. Base 12 is better!

        Binary is very good for counting with your fingers. With both hands you can count to 1023. One hand is 31, which is still usually more than you typically need to count. It’s also trivial to do once you know how binary works. It takes very little thought, though potentially the decoding could take a bit depending on your proficiency.

            I agree it can feel weird, but first this isn’t how we are used to doing it so it hard to compare, and also normally we want our fingers in very precise positions (probably because it’s easier to show other people). When doing binary I feel it’s easier to ignore precise positions. I just use the half of my finger after the middle knuckle and let my fingers move as they please. We only need to track up or down, so it doesn’t need to be precise.

            Practice helps. I’m not good at it, but I can manage it fine at this point. For sure it’d doable, but I rarely have to count, and when I do I can generally do it in my head fine. I could see myself using it maybe if tracking a large number over a long time, but I don’t see that case ever coming up organically.

          I find it useful if I’m counting only specific instances of something that meet some criteria. That way my brain can focus on picking out the right things and not have to worry about keeping the current count in mind. I use the method with your thumb on each segment of your fingers though, so you can get up to twelve with one hand and 156 with both

        Common denominators. You can divide base 12 into half, thirds, fourths, and sixths and still use integers. I find thirds to be particularly useful, so base 16 is out. Base 60 can do it, but that’s getting unweildly.

            In any Base-x system, one digit goes up to x - 1 (with base > 10 we use alphabet letters), then the next digit (to the left) is incremented.
            So in our normal Base-10 system, you count up from 0 to 9 and then add a digit in the front and reset the other digits to get 10.

            This means, that in every Base-x system ‘10’ equals x.
            So you can make the “There 10 types of people …” with every base as ‘10’ in Base-2 means 2, 3 in Base-3 and so on.

    Huh, that’s a good point. A better universal naming system would be something like “Base x+1”, with x being one integer lower than 10. So humans would use Base 9+1, and the alien would use Base 3+1.

    *This has been on my mind all day and the more I think about it, the more obvious it becomes how fundamentally terrible the name “Base-10” is. How did this never occur to the people who coined the term? Even the system I suggested is flawed as it’s still trying to incorporate the same bad logic.

    A better system would be something like Base 9, stopping shy of the respective 10 in each system, or if it needs to be clarified, Base 9+0, as 0 is the extra digit in the first place, not 10.

      we’d only be able to represent bases for numbers with one digit though because what does base 15+1 mean? the 15 could be in any base higher than 5. the clearest way would probably be to just represent it with lines or something “base ||||||||||”

        It’s only 15 to us because we use base 10 (or 9+1). Like how we have 4 through 9, but that aliens in the picture only count up to 3.

        In the case of a mismatch, the culture using the higher base would just translate down (Base 21+1 in the given scenario).

        Single units would probably be the simplest method, but also wildly impractical as the base gets higher. You really want to count each digit just to figure out someone uses Base 100?

        I think that would confuse things more than it would help. It’s base 5, unless it’s base 10, unless it’s base 50, etc. And then there’s the rules designating numbers 1 below certain other numbers, or 2 below, depending on the system being used. That’s a whole web of complications when communication is already murky.

        One glyph to one integer communicates the number system being used more clearly.

    Wow I never thought about that.

    But it is always like this:

That can represent a number by the sum of their positional digits:

number = sum(d_i * b ^ i)
   where i is the position index and d_i is the digit at this position. (note: index starts with 0, from the least digit farthest to the right)

    So the (decimal) number 4 in base 4 is then

    1×4¹ + 0×4^0 = 10

    And (decimal) number 8 in base 8 is

    1×8¹ + 0×8^0 = 10

    And 10 in base 10:

    1×10¹ + 0×10^0 = 10

              10 as the first overflow of digits is not a clear vlaue, it depends on the notation because its base is unclear.

              Ten as the English word is 100% defined. The issue is we translate seamlessly between the word and number, but there really is no confusion when writing ten. 10 in hex has a different english word: sixteen.

              English number names are mostly decimal-based, but their values are still fixed. Ten isn’t the word for “the first time our number system overflows”, it’s an amount.

              So I disagree. Ten will always be (…) this many, because it’s an English word.

      “ten” is a fixed amount in base 10. A base 4 user may have an entirely different naming system for numbers above 3, so “ten” (which is written as 22 in base 4) could be twenty two, twoty two, dbgluqboq, or Janet. But similarly to how we don’t have a single syllable, dedicated number name for decimal 22 (as in, it’s composed of the number names ‘twenty’ and ‘two’), they may not have a single syllable, dedicated number name for decimal 10 (which is ‘22’ in base 4).

          EDIT: I see where you’re coming from: base 10 English also has a unique name for something that is not 0-9 or a power of 10 - however, the only reason to this is that they are from base 12. Obviously base 12 has unique words for numbers below the base. But not numbers above it (apart from maybe powers of 12). Which further proves the point.

            My point is the difference between number system and language. We’re seamlessly converting back and forth while writing this, but there’s a specific amount in our heads that we’re trying to communicate, either by word or by number. The number is ambiguous only if you don’t know the base, while the word is ambiguous only if you don’t know the language. The meme is - presumably - in English, and they’re talking (in speech bubble form), so the misunderstanding doesn’t really happen. it’s only when a secondary ‘language’ is introduced - the numbers - that it is possible.

            Ten in particular, which we usually write as a two digit number because of historical and biological context, still uniquely describes a certain amount without any relation to it being written as the first two digit number. In any language, you wouldn’t translate to one two three ten just because they usually write in base four, you’d translate to whatever their word for the number is that you’re trying to translate.

      even when written out non base ten systems, are still possible to be non base ten.

      It’s only base ten when you convert from one base system to another. We are merely referencing between two base systems when we say that 4 bits is “16” because there are 16 possible options there. 16 is just our conceptualized version and conversion of that base system, in ours. You can read binary as if it’s just powers of 2, it’s incredibly trivial.

      octal and hex are the best example of this, because octal skips numbers while counting. Hex introduces letters. Neither of which fly even remotely sanely through base ten. Unless you’re converting.
