Binary Addition Calculator

A binary subtraction calculator computes the difference between two binary numbers, showing borrow bits and the result in binary and decimal.

Binary subtraction follows rules: 0-0=0, 1-0=1, 1-1=0, 0-1=1 (borrow from next bit).

A borrow bit is taken from a higher bit position when subtracting 1 from 0.

Subtraction using two's complement: A - B = A + (NOT B + 1).

Subtraction using one's complement: A - B = A + NOT B + carry.

The minuend is the number from which another is subtracted.

The subtrahend is the number being subtracted.

The difference is the result of subtraction.

Unsigned subtraction handles positive numbers only.

Signed subtraction handles negative results using two's complement.

Underflow occurs when the result is negative and exceeds available bits.

Direct subtraction compares bits and borrows as needed.

Subtraction using complement methods (one's or two's).

Borrow propagates from higher bits when needed.

A half subtractor subtracts two bits, producing difference and borrow.
