The two numbers that satisfy both conditions are -4 and -5. When multiplied together, -4 × -5 equals 20, which does not meet the requirement. However, if we consider the correct numbers, they are 1 and -10. When multiplied, 1 × -10 equals -10, and when added, 1 + (-10) equals -9. To meet the criteria, the correct pair is 4 and -5, where 4 + (-5) equals -1, which does not meet the requirement either. Upon reevaluation, the numbers do not exist that fit both conditions simultaneously.
