Hexadecimal numbers are created using base 16. This means that there are 15 digits to use before carrying over into the next digit’s place. A hexadecimal number can be converted to decimal by following the example table below. Hexadecimal numbers are used to shorten otherwise long numbers in decimal, and can be seen in day to day life when selecting specific colors online, as there are so many specific colors to choose from.
Since Hexadecimal has 15 digits, but decimal(what we use every day) only has 9, you may be wondering, then what are the other digits? You may even think the next digit after 9 is 10, but that takes up two digit spots. Instead of the continued use of numbers, hexadecimal actually uses letters to convey what would normally be double-digit numbers! These letter representations can be seen below.
