# Hexidecimal

Hexadecimal is a number system that uses 16 different symbols to represent values. It is commonly used in computing and digital systems because it is a more compact way of representing large numbers compared to the decimal system. In this blog post, we will explore the basics of the hexadecimal system, how it works, and its applications.

The hexadecimal system uses 16 different symbols to represent values. These symbols are the digits 0 to 9 and the letters A to F. The letters are used to represent values that are greater than 9. For example, A represents the value 10, B represents the value 11, and so on, up to F, which represents the value 15.

The hexadecimal system follows the same principles as the decimal system. Each digit in a number represents a power of 16, just as each digit in a decimal number represents a power of 10. For example, the hexadecimal number 2A6C represents:

2 x 16^3 + 10 x 16^2 + 6 x 16^1 + 12 x 16^0 = 8,712

The above calculation can be done by multiplying each digit in the number by the corresponding power of 16 and adding the results.

The hexadecimal system has several advantages over the decimal system, particularly in the field of computing. One of the main advantages is that it is a more compact way of representing large numbers. For example, the decimal number 1,234,567 can be represented in hexadecimal as 12D687. This makes it easier to work with large numbers in computer programs.

Another advantage of the hexadecimal system is that it is easier to convert to and from binary, which is the base-2 number system used in computing. Each hexadecimal digit can be converted to four binary digits, making it easier to represent binary numbers in a more compact way.
