WebApr 13, 2024 · A subtractor would be the same circuit as an adder by representing a negative number as two’s complement. In short, subtraction is thought of as “adding a negative number.” For example, if you want to calculate 7–5, you can think of it as 7+(–5). To turn a binary number into two’s complement, “flip the bits and add 1.”
