The following lists 4 main attributes of this numeration system.
First, it uses 10 digits or symbols that can be used in combination to represent all possible numbers.
The digits are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
Second, it groups by tens, probably because we have 10 fingers on our two hands. Interestingly enough, the word digit literally means finger or toes.
In the Hindu-Arabic numeration system, ten ones are replaced by one ten, ten tens are replaced by one hundred, ten hundreds are replaced by one thousand,
10 one thousand are replaced by 10 thousands, and so forth...
Third, it uses a place value.
For example, in the numeral 4687, there are 7 ones, 8 tens, 6 hundreds, and 4 thousands.
Finally, the system is additive and multiplicative. The value of a numeral is found by multiplying each place value by its corresponding digit and then adding the resulting products.
Place values | thousand | hundred | ten | one |
Digits | 4 | 6 | 8 | 7 |
