Is binary addition is related to logic gates in digital electronics?

Binary subtraction is also similar to that of decimal subtraction with the difference that when 1 is subtracted from 0, it is necessary to borrow 1 from the next higher order bit and that bit is reduced by 1 (or 1 is added to the next bit of subtrahend) and the remainder is 1.

a basic operation in computer arithmetic. The easiest way to subtract two binary numbers is to make one of the numbers negative and then add them. Circuits for doing binary addition are readily constructed with logic gates (see binary addition). The negative counterpart of a binary number is called its 2-complement.

For decimal subtraction, the basic facts are things like 5 – 1 = 4, 9 – 8 = 1, and 18 – 9 = 9. In each case, the answer is a single-digit, nonnegative integer.

Most of the facts are “single-digit minus single-digit” problems, but some are “double-digit minus single-digit” problems (the double digits are the numbers 10 through 18).

The latter represent cases of borrowing, which is the process by which negative answers are prevented.

After the points are aligned, subtraction proceeds from right to left

Red marks indicate borrowing. If a non-zero digit is borrowed from, it is crossed out, one is subtracted from it, and the decremented digit is written above it; a 1 is then placed next to the digit in the borrowing position, making it a two-digit number.

a zero digit is borrowed from, the borrow “cascades” until a non-zero digit is found.

Some people refer to this as the “American method” (although this is just one variation of it — see Salman Khan’s video, for example). Whatever your method is though, you can apply it to binary numbers.

The first three are the same as in decimal. The fourth fact is the only new one; it is the borrow case. It applies when the “top” digit in a column is 0 and the “bottom” digit is 1. (Remember: in binary, 10 is pronounced “one-zero” or “two.”)

Since there are lots of 0s in binary numbers, there can be lots of borrows — and lots of messy looking cross-outs.

Notice that I didn’t discuss the number base when describing the algorithm; it is base-independent. Nonetheless, I could have talked about powers of ten and powers of two, and how the process can be visualized by regrouping
