no- it depends on the absolute values of the numbers. The sum is negative only if the absolute value ( the value without the sign) is larger than the positive number.
example -98 + 100 is positive because 100 is larger than 98.
-100 + 98 is negative because 100 is larger than 98.

Is the the sum of a negative number and a positive number always positive?
No
How can you decide if the sum of two numbers is positive negative or zero without actually calculating the sum?
The sum of two positive numbers is always positive, and the sum of two negatives is always negative. If you have a positive and a negative number, there sum can be either, so look at the absolute values to decide. For example -3+2=-1. Since all you care about is the sign, look at the absolute value. If the negative number has a greater absolute value, the sum is negative and if the positive number's absolute value, which is the number itself, is bigger, the sum is positive. If the absolute values are equal, the sum is 0.
Dose a negative number plus a negative number equal a positive number?
No. The sum of two negative numbers will always be a negative number. If, however, you multiply the numbers, their product will be positive.
Negative number plus a positive?
If the negative number is bigger then the sum would be negative.If the positive number is bigger then the sum is positive.
Is the sum of two integers always positive?
No. The answer depends on the context in terms of which the numbers are considered to be opposite.
