instead of 12 i think 1100 is negative and in 1's complement form which is -3 in decimal

Given the two unsigned numbers X= -58 and Y= 65 (both in deciaml) perform subtraction X-Y using 1’s complement method. how to do this my answer comes -124 but it should be -123

@@Im_DJ I think sir is doing that for us to understand that 1000 is -7 and not +8 as most of us would assume that, the answer is what we actually got just by directly adding two numbers A and B, if you have +7->0111 do 1's comp you get 1000, so in 1's complement representation 1000 represents -7.

I have a doubt. Pls anyone clear it. In example 2 we are doing (5-12). So ans should be -7... From the addition result comes 1000 which is -7 in decimal. But complementing makes it +7. According to decimal -7 should be the ans not +7

What is the end around carry in a 8bit answer?

TYSM

Can you post the answers so I can check if I did it right pls

To clarify further on Example 2 at 8.30, we may want to take 1 extra bit 1) The 4 bit number system has range [-(2^3)-1,+(2^3) -1)] = [-7,7]. Then the number 0101 is 5 as expected, but 1100 is actually -(0011) or -3 Then (0101)2 - (1100)2 = 5-(-3) = 8, which again cannot be represented in 4 bit system. So we consider a 5 bit system 2) The 5 bit system has range [-15,15]. So 00101 represents 5 and 01100 represents 12 (00101) - (01100) = (00101) + (10011) = 11000 = -(00111) = -7 in the 5 bit system

You are correct in clarifying. Example 2: (0101)-(1100) gives you 1000 with a carry of 0. The carry of 0 tells us our answer will be negative. It also tells us the magnitude will be the 1's complement. Taking the 1's complement of 1000 (which is 8), gives us 0111 which is 7. The carry gives the sign. The magnitude after the complement is taken.

could u you tell why you have wriiten -(0011) ? does writing - have sense with binary because negative is essentially 1's complement ? also why do we invert the answer when there is no end carry because answer should be negative and if you invert the answer then it becomes positive , so why do we invert the final answer then ?

I have a question, in previous vid. to take the negative of +5 (0101) we take 2's comp.(1011=-5) but here when we are substracting we add the neg. version of it taking 1's comp. I am a bit confused about computing the neg. version of a binary number, should i take 2's or 1's comp?

as per my understanding, it didn't end up with 0111 as answer. The final answer is 1000 itself. It was just to show that 1000 here is negative and in 1's complement form so that people don't consider it as 8. 0111 is +7 (base 10) so 01000 is -7 in 1's complement form. Please correct me if I'm wrong.
