Abstract
Two conditions, which are of particular importance when performing addition and subtraction, are carry and overflow. They are conditions which affect bits in the flag register so that they can then be tested by conditional jump instructions. The carry and overflow conditions are used as an aid in determining whether an arithmetic operation has been carried out correctly.
