simply by complementing x input before applying to and gate for generating carry
The half adder is an example of a simple, functional digital circuit built from two logic gates. A half adder adds two one-bit binary numbers A and B. It has two outputs, S and C (the value theoretically carried on to the next addition); the final sum is 2C + S.
A 5-bit adder can be used as a subtractor by utilizing the concept of two's complement. To perform subtraction, you can invert the bits of the number to be subtracted (the subtrahend) and add 1 to it, effectively converting it to its two's complement. Then, you input this modified value along with the minuend into the 5-bit adder. The result will be the difference of the two numbers, allowing the adder to function as a subtractor.

simply by complementing x input before applying to and gate for generating carry
A binary parallel adder is a digital function that produces arithmetic sum of two binary numbers in parallel. It consists of full-adder combinational arrangement thus, the output carry from one full adder connected to the input carry of next full- adder.
An adder-subtractor is a circuit capable of subtracting or adding binary numbers. The application of a 4-bit adder and subtractor is for use as part of the core of an ALU, or arithmetic logic unit.
design a one bit slice of the adder subtractor and iterate it through all 12 bits.
A subtractor can be designed using the same aproach as that of an adder ,subtractor are usually implemented within a binary adder for only a small cost when using the standard two's complement notation,by providing an addition/subtraction sector to the carry in and invert the second operand. A subtractor using of diffrencate bits.

let us consider three inputs a,b,c and their sum as s, difference as d and carry as c and borrow bin full adder circuit :-s= a (XOR) b (XOR) ccarry = ab+ac+bcin full subtractor :-d= a (XOR) b (XOR) cborrow b = a'b+a'c+bcso on observing these two we notice that sum and difference are one and the same coming to carry and borrow the only difference is to obtain borrow from carry just complement the input a

The 7483 is a 4 bit full adder and a 0 on C will make it act as a subtractor
it can be used in op amp circuits, that is as comparitors or differentiators

Advantage:1:To overcome half subtractor, full subtractor comes into play
A half-subtractor lets you borrow out, but not borrow in. A full subtractor is made by combining two half-subtractor and adding an OR-gate. (lets you both BOR_in as well)
To make a full subtractor, you need an XOR and a NAND gate.
