Last H.W. ques is a bit tricky. Here is its solution: (83)+(34) 10000011+ 00110100= 10110111. So divide it in 4 bits then we get 1011 and 0111. Here 0111 i.e.79 . So the problem here is when we add 0110 i.e. 6 in the answer we will get wrong answer because 10110111+ 00000110 Here we are adding 0110 i.e.6 in the side of seven i.e.0111 and in sir's problem we were adding 0110 in the side of 13>9. So we only have to take number 11 out and write 1011+ 0110= 10001 now just merge this result and seven we get 100010111 when we write this result in 4 bits we get 000100010111 so its decimal form is 117.

Your Answer 3 is wrong because here the addition is greater than 9 and there the final carry is 1 (not 0 ok, if you have 0 in your final carry, you can add 0110 , )
Another example could be when you also have to watch out for when the carry (after adding 6) from a digit in units place makes the digit in the tens place (and/or a carry from a digit in tens place makes the digit in the hundreds place) exceed 9, and so on. You need to add 6 more than once. eg 57+46=103, and 657+346=1003, etc. eg 1 57+46 0101 0111 0100 0110+ ------------------ 1001 1101 (initial sum) 0110+ (add 6) ----------------- 1010 0011 0110+ (add 6) ------------------ 0000 0011 Final Carry=1 0001 0000 0011= 103

After error correction (i.e add 0110) if msb of the number generates a carry it can be considered as a bcd bit, which is happening in the home work problem 4.

In the last homework question we don't need to add 6 at all as 7 which is less than 9 with final carry 0 it's correct then 11 which is indeed greater than 9 but final carry is 1 which is also correct as mentioned in the lecture. So 83 + 34 which is 117... We get the same result by making pairs of 4.

yeah, but then you are representing two digits (11) with a single bcd code (1011) and it isn't even a valid bcd code.That makes no sense
Sir how can u say about final carry as 0 and1
i love neso academy
you are the best of the best
What is meant by the final carry ?
I have a doubt that . should I have to add 6 to every fours bits in BCD addition or only first time only . please clear my doubt

how is the diagram of (for example 83+34) in BCD addition? please help me
which app are u using
Did anyone plz give answer for 48+ 58 in bcd addition..
In the last question, the left pair's sum was greater than 9 ..? Obviously, the answer is 117 but what bout this case ?
Why the final carry is 0 in first example ?
For those wondering, you have to only add 6 once and then not again if the answer again in bigger than 9, just group them into bits of 4.
which software you use,can you please tell me?

What happens if sum is equal to 9?Do we then differentiate on the basis of final carry?
@kyukyahua

Adrija Ray Chaudhuri It still remains a binary number with no carry. Checkout the binary code and see whether it is equal to the BCD code. Whenever you get a decimal number of base 10, convert each digit to it's respective binary. The amount of bits will be 2^4n.
sir what if carry is 1 and sum is > 9?
sir, what would happen when final carry is 1 and no is greater the 9?

no such case exist, adding two single digit bcd no. and getting sum greater then 9 and carry 1
@user-fg6ro
6 жыл бұрын
any 4 bit number greater than 9 is actually A (1010b) to F (1111b) in hexadecimal. Hence there cannot be any carry. But when the sum exceeds F, the sum will be 0, and there will be a carry. So your case does not exist.
divide your final answer to 4-bit blocks and consider each 4-bit result with the 1,2,3 conditions. for example 68 + 79 = 0110 1000 + 0111 1001 = 1110 0001 . For last 4 bit (sum 9 F.C:0) add 0110 so the correct answer will be (wrong answer) + (0110 each of the 4 bits), so 1110 0001 + 0110 0110 = 1 0100 0111 is also equals 0001 0100 0111 = 147 in decimal --> Correct answer. Good luck.
I have some prob sir, u added 8+9 ans would be 17 why are separating sum and final carry,I think two conditions are sufficient if sum >9 then add 6 if not then not add 6
