The possible combinations is If you doubt the validity of this counting, look it up -- it's pretty common knowledge. Well, if you define that finger has 3 joints, a thumb is not a finger. In fact, it is more rational to assume that thumb is something else as saying, that finger sometimes has 2 joints, sometimes 3.

I don't think they would use 3-digit groupings and commas, though. When writing in other bases I always use a thin-space for grouping and group 4 digits typically.
Historicly, octal computers did not use 8 bit words, but 9. Values were 18 and 36 bit sizes iirc. Rogelio Molina Rogelio Molina 3, 12 12 silver badges 23 23 bronze badges.
Most of that nonsense was swept away by the French Revolution in France, adopting a "modern, rational" system of units metrical system , which Napoleon's conquests spread over most of Europe. Today it is slowly working it's way across even recalcitrant countries like Britain and the US. It has already become universal in science.
On a side note, I am all in favour of the metric system and I look forward to see it adopted globally. Just something curious. In Britain I assume everybody used their foot as a rough measure, that was standardized sometime when precision became a necessity. Same for inch in Spanish "pulgada", i. Upcoming Events.

For example: The tenths are 3 places to the right of the hundreds. Whole Numbers The base ten place value number system has a repeating naming pattern. The pattern of ones, tens and hundreds names firstly the units, then the thousands, and then the millions etc. The convention of including a space between each family or group helps us read the number. The decimals in the naming pattern have equivalent decimals which are easier to read.
For example 10 thousandths is equivalent to 1 hundredth. So, although the naming pattern continues to the left of the decimal point the convention is to name the decimal by the place value column furthest to the right. For example, 0. Often decimals are simply read as a string of digits, with 0. Encouraging students to read decimals by using their place value supports them in their development of number sense. The role of the decimal point is to indicate the units or ones place in a number and it does that by sitting immediately to the right of that place.
But what happens when we have used up all of those digits? Like before, we count the number of times we run out digits, and we call each one an hour. Counting in this way is called sexagesimal. We inherited the sexagesimal system from the Sumerians more than 4, years ago. It has lasted for so long because you can easily divide a number into two, three, four, five or six equal parts.
Try dividing an hour into three equal parts and you will see there are 20 minutes each. Now try dividing a dollar into three equal parts and you will see there are 33, 33 and 34 cents each. Our world uses many different place-value number systems, and they are all useful for different reasons.
