• [<$>] Change the subtracted number and the subtracted number to positive numbers; perform subtraction of two positive numbers; Take the sign of the result according to the sign of the subtracted number or the subtracted number depending on the magnitude of pounding them

• [<$>] Change the sign of the subtraction number and then perform addition between two signed integers.
