*Decimal System*

**The decimal **number system also is known as the Base 10 numbering system because it is based on 10 ranging symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. In the decimal system, every digit holds its own position along with the decimal point. I.e. the number 326.34 has 4 in the Hundredths position, 3 in the Tenths position, 6 in the Unit position, 2 in the Tens position, and 3 in the Hundreds position.

*The decimal number system* is also one of the ancient numeral systems, whose roots are in the Hindu-Arabic numeral system.

*Hex System*

**Hex** or hexadecimal is a number system with base 16. This number system is especially interesting because in the decimal number system we have only 10 digits to present the numbers. As the hex system has 16 digits, the first 6 letters of the English alphabet used to represent extra 6 digits. So, hex digits are 0,1,2,3,4,5,6,7,8 and 9 A, B, C, D, E, F.
