"WebBINARY ADDER–SUBTRACTOR The most basic arithmetic operation is the addition of two binary digits. This simple addition consists of four possible elementary operations: 0 + 0 = 0, 0 + 1 = 1, 1 + 0 = 1, and 1 + 1 = 10. The first three operations produce a sum of one digit, but when both augend and addend bits are equal to 1, the binary sum " - Signed 4-bit binary adder/subtractor
