Addition of hexadecimal numbers can be easily carried with the help of the above table.

Following example illustrates the use of the table.

Evaluate: (B A 3)16 + (5 D E)16

Solution:

We note from the table that

 3 + E = 11A + D = 1717 + 1 (carry) = 18B + 5 = 10 10 + 1 (carry) = 11 1 1 carry      B A 3      5 D E          1 1 8 1

Hence the required sum is 1181 in hexadecimal.
