Yes, Hindu-Arabic system have only 9 symbols.
Because we use the decimal system which has only ten symbols - for the numbers 0 to 9. In the decimal system, every time you get to a power of ten, the number starts one further place to the left.
The symbols used in the Hindu/Arabic system of numbers are; 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0.
Hindu-Arabic basic numeral symbols are: 0 1 2 3 4 5 6 7 8 and 9 Roman basic numeral symbols are: I V X L C D and M
There are an infinite amount of numbers. However, there are only 10 numeric symbols, 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. The symbols are independent of the system. These are the Latin symbols, now internationally recognised, however many cultures still use their own traditional symbols. Punctuation symbols are also used to format a number, such as the radix point (.) and factors of 1000 (,) however some cultures, particularly non-English speaking European cultures, use these symbols the other way around.
The original Greek numeral system was the Aegean numeral system, which used separate symbols for 1, 10, 100, 100 and 10000. This was replaced by the Attic numeral system, which was quite similar to the Etruscan/Roman numeral system (which derived from it), with separate symbols for 1, 5, 10, 50, 100 and so on. This was then replaced by the Ionic system, which used 27 separate symbols for the units 1-9, the tens 10-90 and the hundreds 100-900.
9
The decimal number system uses 10 different symbols to represent a number. The 10 different symbols are 0 to 9. It is a base 10 system unlike binary which is base 2 ( 0 and 1).
Because we use the decimal system which has only ten symbols - for the numbers 0 to 9. In the decimal system, every time you get to a power of ten, the number starts one further place to the left.
It is called Hexadecimal
Primitive digits (symbols)in a base 10 system
0 - 9 plus A - F
The symbols used in the Hindu/Arabic system of numbers are; 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0.
I'm not sure I'm only 9
There are 10 digits in our number system. The symbols 0,1,2,3,4,5,6,7,8,and 9 are the digits used to create numbers.
There are 10 symbols in the system and they are... 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0.
The hexadecimal system is the fourth system based on powers of two that use the decimal digits 0 through 9. Since 16 symbols are needed the letters a through f are added. The next system would use 32 symbols so 22 additional symbols would be needed.
