The sum of a positive number and a negative number is positive when?

The sum of a positive number and a negative number is positive when the magnitude of the positive number is greater than the magnitude of the negative number. In other Words, if the positive number is larger than the absolute value of the negative number, their sum will be positive. For example, if we have 5 (positive) and -3 (negative), their sum is 2, which is positive. Conversely, if the negative number's magnitude is greater, the sum will be negative.
