2's Complement Arithmetic
I this video, how to perform the addition and subtraction of signed binary numbers using is explained using examples.
The advantage of 2's complement arithmetic is that the subtraction can be performed in a very similar way to the addition of two numbers.
Condition of Overflow:
While performing the addition or subtraction using 2's complement arithmetic, one should be careful about the range.
If the addition or subtraction is out of the n- bit 2's complement representation range then the result after addition or subtraction will be invalid and it is the case of overflow.
In this video, the condition of overflow is explained with the help of few examples.

Addition Note. Usign MSB we can decide theather the addition is right or not. Note. 2's complement of negative numbers are +ve. Case 1 - (Both are +ve) Add normally. (After addition two n bit numbers if the sign bit is 1 then that's the case of overflow). Case 2 - (One is +ve another one is -ve, + > -) Represent the negative number in 2's complement form and then do normal additition. Case 3 - (One is +ve another one is -ve, - > +) Represent the negative number in 2's complement form and then do normal additition. Case 4 - (When both numbers are negative) Convert both numbers in 2's complement form then add normally. (After addition two n bit numbers if the sign bit is 0 then that's the case of overflow). Subtraction P-Q = P + (2's complement of Q; with sign of Q)

@FensterwischerX Жыл бұрын

As far as I got it it's because you basically substract a positive value since subtracting a negative value would equal an addition. And to be able to perform a substraction by adding you have to translate it.. Not 100% sure though

We are adding the 1 to the one's compliment of 6 (Just ignore the 00110 that's the representation of +6, we add 1 to the one's compliment of the number in order to find 2's compliment.)

How to know how many bit should I represent -25 and -28 so that result is not invalid?

@ALLABOUTELECTRONICS 8 ай бұрын

Using N-bits, we can represent -2^(N-1) to 2^(N-1) - 1 numbers in 2's complement form. For example using 4 bits, we can represent -8 to +7 in 2s complement form. Now, if we want to properly add/subtract any two numbers in this range , then we need at least N+1 bits. For example, if you want to add/subtract -8 and -8 (The result is -16), then you need 5 bits to correctly represent them. Now, for your addition/subtraction, you can calculate the required number of bits accordingly. 😊

Then sir, what we will do after after answer will be invalid? Do we leave it there or take carry bit also as an anwer?

@ALLABOUTELECTRONICS 8 ай бұрын

I think you mean when there is a condition of overflow right !! Yes, when there is a condition of overflow, then we will get the invalid result after the addition/ subtraction. And if we want to perform the proper addition / subtraction, then we need to add one more bit while performing the arithmetic operation. If there is no provision for adding the additional bit, then simply the overflow bit in the arithmetic circuit will become high. Which indicates that the result is invalid.

@kottelkannim4919 Жыл бұрын

A: I just checked the no-carry case for 3 - 5 , in 5 bit form: (3)base10 = 00011 (5)base10 = 00101 (-5)base10 = 11011 (3)+(-5) = 00011+11011= 00011 + 11011 ===== 11110 The 2's complement of the sum is 00010, namely (2)base10. so 11110 is (-2)base10 which is the expected result.

20:04 as far as I got it you can basically use any number of bits. A bit is just the possibility to represent a 0 or a 1. Remember that the first digit is used to indicate the sign + or -. Does that help?

@davidosibodu8760 Жыл бұрын

all the calculation you are saying are invalid are not so, you just need to use the carry bit. For example when you did -5 - 13 and you got 101110 but you disregarded the left most bit you would still get - 18 because -32 +8 +4+2 = -18 anyway.

@ALLABOUTELECTRONICS Жыл бұрын

What you are saying is true. But generally, in actual hardware implementation, the length of the register is same. (for storing the numbers, and result). Assuming the register length as 5-bit (since we are performing 5-bit 2s complement subtraction), the result will also be stored in 5-bits. And the additional carry bit is used to check the condition of overflow.
