Last question for the day someone plz me plz and you

I'm not sure what you mean but the opposite of an integer is its addtive inverse. Meaning, if the integer is positive, the result is its negative, (e.g. additive inverse of x when x > 0 is -1*x = -x)
When x is negative, the additive inverse is positive (x when x < 0 is -1*-x = 1*x = -x)

There is no question, there is just the answer.
