**I'm assuming you meant "Negative plus Positive"**
Honestly, when you add a negative number to a positive number, the outcome depends on the numbers added together.
For example, if you add -10 with 5, the sum is negative because the negative number is larger.
And on the other hand, if you add -5 and 10, the sum is positive because the positive number is larger.
Therefore, to determine whether a sum will be either positive or negative, see if there are larger negative numbers compared to positive numbers and vice-versa.
