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
We note from the table that
3 + E = 11
A + D = 17
17 + 1 (carry) = 18
B + 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.
Subtraction of hexadecimal numbers can be accomplished by using complement method. Although it is not a very simple method computers use it very efficiently.
These above explanation will help you to understand the concept about hexadecimal addition and subtraction.
