Till 0 to 9 it is just simple procedure i,e; just add 3 to the binary(BCD to be precise) eqivalent of the number Ex: 0-> 0000+0011=0011 and so on For 2 or more digit numbers first we need to covert it into BCD and add +3 to each and every digit Ex: (0001 0011)BCD+ (0011)= (0100 0110) (Here we have to add +3 to every digit) BCD and Binary representation are not same.
