Different Counting Systems Mapped
Numeral systems are collections of symbols used to represent small numbers together with systems of methods for producing larger numbers.
When it became essential to count frequently to numbers larger than ten, the numeration had to be simplified and systematized; this was typically done through use of a group unit, just as might be accomplished nowadays by counting 43 eggs as three dozen and seven. The earliest numerals of which there is an unquestionable record were simple straight marks for the small numbers with some particular form for ten. These symbols emerged in Egypt as early as 3400 BCE in Mesopotamia as early as 3000 BCE.
Of course, the special position occupied by 10 stems from the number of human fingers. It is still apparent in modern usage in the logical structure of the decimal number system and in the English names for the numbers.Currently, there are still existing many different numeral systems.
The map below created by mapologies shows the last double-digit number (99) in different counting systems.
