    Btw: I'm Aware, it took a longer time to recognize that "Zero" also exists.

    I've recently been watching some YouTube videos late at night about the Sumerian Sexagesimal (base 60)[^] system. It's extremely interesting. The Sumerians absolutely knew about zero.. but they did not have a symbol for it. In all of the clay tablets with calculations requiring a zero... there is a blank space where the number zero should be. That makes perfect sense to me... with zero being NULL.

    There is some very interesting speculation about west-to-east (from Egypt) cultural transmission of iconography and the mathematical basis for weights and measures in this book on the weights of Burma (now Myanmar): Note: CP editor is not displaying pasted in links as expected ... https://www.amazon.com/Earth-Heaven-Animal-Shaped-Weights-Burmese/dp/9747551209 It's an out-of print book for a specialist, and ridiculously expensive, now. And, frustrating to read because some very grandiose theories are proposed, but sources are not annotated satisfactorily.

          Is it really because we have ten fingers? Would it then not be more logical to use then a system based on 11?:confused: :laugh: Btw: I'm Aware, it took a longer time to recognize that "Zero" also exists.

                      70 = soixante-dix 80 = quatre-vingts 90 = quatre-vingt-dix And danish: 50 = halvtreds 60 = tres 70 = halvfjerds 80 = firs 90 = halvfems In Paris you have (Or had) l’Hôpital des Quinze-Vingts, which used to have 300 beds. Mostly remnants today, the Swizz (and if I recall correctly the Belgians) have gone full decimal. Switzerland uses septante for 70, octante or huitante for 80 and nonante for 90 In english there are small rests of it too: "Four score and seven years ago our fathers brought forth on this continent a new nation, conceived in liberty, and dedicated to the proposition that all men are created equal."

                        It is almost correct. Belgians still use 80 (quatre-vingts). But you are perfectly right about 70 and 90.

                                  I can think that Zero does not offer much trade use? You either trade or not. If i give you 10 for somthing of 5 value, you give me 5 back. but if i give you 10 for something of 10 value, you don't give me anything back. Nothing/Zero is similar. - yes its zero, but for the purpose of the trade, nothing. contrast with mathematics, 2x0 - not sure what trade situation except the trader turns up with nothing to trade. I'm not going to work out some maths to know he aint got anything to trade.

                                    The dozen, I suspect, is also based on fingers. It's a system that emanates from East Anglia.

                                    98.4% of statistics are made up on the spot.

                                      There is a known bug with link paste currently being reported on the Buggs%Suggs forum.

                                      «... thank the gods that they have made you superior to those events which they have not placed within your own control, rendered you accountable for that only which is within you own control For what, then, have they made you responsible? For that which is alone in your own power—a right use of things as they appear.» Discourses of Epictetus Book I:12

                                        Is it really because we have ten fingers? Would it then not be more logical to use then a system based on 11?:confused: :laugh: Btw: I'm Aware, it took a longer time to recognize that "Zero" also exists. From what I remember it was somebody from India who recognized this fact first. [Edit] Try to imagine we would have only one finger...

                                        11 is far from logical. Afterall, using an 11-based system would exclude roughly half of the population from counting.

                                          The dozen, I suspect, is also based on fingers. It's a system that emanates from East Anglia.

                                          98.4% of statistics are made up on the spot.

                                          I read something on this once. From what I recall, 12 is used for dozen and timekeeping because it was easier to break down into fractions with no remainder. 10 is divisible by 2 and 5 whereas 12 is divisible by 2, 3, 4, and 6.
