a is a positive number.
b is a negative number.
What kind of number is the sum of b and a?
We will illustrate with an example:
Let's assume that a is 1 and b is -2
1+ (-2) =
1-2 = -1
Answer: Negative
Now let's assume that a is 2
and b is -1
2+(-1) =
2-1 = 1
Even though the operation is negative, the number remains positive.
That is, if the absolute value of the positive number (a) is greater than that of the negative (b), the result will still be positive.
As we do not have data regarding this information, it is impossible to know what the sum of a+b will be.
