in this video will discuss about the BCD arithmetic operations in general if you are multi if you are adding to BCD numbers the result will not be satisfied the correct BSC result in order to satisfy the current wizard result are correct the b c d result we need to add 6 in case of addition operation in case of subtraction operation we have to supply the 6 for lower back as well as the highest paid and of course there any chance to generate propagate the auxiliary carry flag are carry flag in the lower and higher bed successively so that according to the rule we may adder subtractor 6 enough for the appropriate operation so for that cause we are using the data and instruction is it is just a commentator and base is decimal I just after subtraction is too important instructions as to be needed for BCD automatic operations only in case of addition and subtraction of the binary coded decimal
