    Every base has ten, but it’s made of two digits

    Binary 0, 1, 10 Ternary 0, 1, 2, 10 … Decimal 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 Hex 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F, 10

    Each has the right count of digits for its base before you go two-digit - binary has two (0, 1), etc

      more precisely, every base has 10, but it’s usually not equal to ten. ten is a fixed value, while 10 depends on the base. you still count normally (one two three four five), even in a base two system. you just write it differently.

        I don’t see the need to bring values into this, this is about the naming of number systems. We really have no more claim to ten being this many (…) than hexadecimal people have to claim ten has this many (…)

          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.

            If you are working in a different number system with other people ten loses its unique meaning just like any word that has another technical meaning.

            In code 0x10 is hex 10 (what you’d call sixteen), but in spoken technical English you don’t need to pronounce the 0x
