Example

1. For 984 and 599, Find BCD Addition

Solution:

984+599 $984+599$ BCD addition (Here we have consider this numbers as decimal value)

Steps for BCD addition

For

A+B $A+B$

1. Add each digit of A and B using binary addition
2. If sum of two digits is more than 9 then result is Invalid BCD and add 6 to the result, Otherwise result is valid BCD.
3. If carry then add it to the next bits

Add

984 $984$ and

599 $599$ using BCD addition

BCD code for 984 :	1001	1000	0100
BCD code for 599 :	0101	1001	1001

Addition :	1110	10001	1101
If Invalid BCD then add 6 :	0110	0110	0110

Addition :	10100	10111	10011

Remaining bits except carry :	10100	0111	0011
Carry :	1	1

Addition :	10101	1000	0011
BCD value :	15	8	3

So final answer of BCD addition is

1583 $1583$
