    It’s a language issue. We say 10 because we don’t have a single digit symbol to represent 10. If a alien with 20 fingers came we wouldn’t recognized their symbols for anything bigger than 9. Base 4 creatures don’t use 4 because after 3 comes 10 for them.

      Base 16 is used all the time in computer science. The symbols for 9+ aren’t arcane or unrecognizable it’s 0 1 2 3 4 5 6 7 8 9 A B C D E F. It’s often written with an 0X in front to indicate hexadecimal or something like 'h for hex and 'd for decimal.

      Examples:

      • 'h7 = 'd7
      • 'hC = 'd12
      • 'hF = 'd15
      • 'h7CF = 'd(7 × 162) + (12 × 161) + (15 × 160) = 'd1792 + 'd192 + 'd15 = 'd1999

        Considering this, for us humans base-10 is base-X

        For the four fingered aliens base-10 is base-4. But they don’t call it base 4 because they don’t use 4 like we don’t use X. They say base-10 because for their language it’s how they say 4. And that applies for all bases.

        should interstellar contact ever actually happen, maths would be the first (and for a long while, probably the only) thing we’d actually be able to communicate in.

        Hey mathematicians, is this a good universal way to communicate number bases? I think y’all would call it 1111111111₁ or something like that

        Fun tangent, on my hands that would be 1023 because I count in binary on my fingers

      Actually, I saw this meme before and I didn’t notice the alien has four fingers. Do we use base 10 because we have that number of fingers??? Is there really a proof of that?

        It’s a good reason for us to use base 10, but in the past many people have not used base 10. However, the bases a society use often are somehow tied to something about the body. As an example (haven’t looked it up for a while, sorry), I think there is/was a group that used base 8, and counted on the gaps between their fingers.
