##### Decimal system

The Decimal numeral system is the most commonly used and the most familiar one to the general public. It is also known as Base 10 numbering system since it is based on those 10 following symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. In this system, every digit has its own position as well as the decimal point. With the decimal point we can represent fractions. For example 107.5 or 3.14. Some countries use "," as a decimal point and others use "."

Many numeral systems of ancient civilisations use ten and its powers for representing numbers, probably because there are ten fingers on two hands and people started counting by using their fingers.Very large numbers were difficult to represent in these old numeral systems, and, only the best mathematicians were able to multiply or divide large numbers. These difficulties were completely solved with the introduction of the Hindu–Arabic numeral system for representing integers. The Decimal numeral system is based and is the extension to the Hindu–Arabic numeral system.
