if both numbers are positive then the resulting answer will be positive.
if both numbers are negative then the resulting number will also be positive.
if one is negative and the other is positive then the number stays negative

64 is positive and -8 is negative (shown by the negative sign)
this one is positive negative resulting in a negative answer.
