Although binary is the way computers communicate on an electronic level, dealing with long strings of ones and zeros is too difficult a task for most human beings. However because of the large numbers that are dealt with in computers, this makes Base10 math unpractical as well. A new form of represent numbers was created based on using 0-9 then, A-F.

The first rule to know about hexadecimal math is that a Base16 digit represents four binary bits.

This makes easy for programmers to represent a byte with two hexadecimal digits. Refer to the chart below to see how Base16 digits are represented in Base10, and Base2.
