Introduction of Number Work:
A number system is a writing system for denoting numbers using digits or symbols in a logical manner.
A number is an arithmetic value used for representing the quantity and used in making calculations. A written symbol like “3,” which represents a number, is known as a numeral.
The numeral system:
- Represents a useful set of numbers
- Reflects the arithmetic and algebraic structure of a number
- Provides standard representation
We use the digits from 0 to 9 to form all other numbers.
| 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
With the help of these digits, we can create infinite numbers.
For example, 12, 3456, 1298, etc.
