# Digital Value: Notation Method of Data

The table on the right is a comparison table of decimal numbers, binary numbers, and hexadecimal numbers.

For example, the decimal number 8 can be represented by 1 digit, but the binary number must be represented by 4 digits.
256 requires 3 digits in the decimal number, and 9 digits in the binary number.

Therefore, we utilize the hexadecimal number to make it easier to handle the binary number.
It is easy to handle because the 4 digits of the binary number can be collectively represented as 1 digit in the hexadecimal number.
