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.

How can you decide if the sum of two numbers is positive negative or zero without calculating the sum?
The sum of two negative numbers is positive and the sum of two negatives is negative. If you have both positive and negative numbers the sum can be either so look at the absolute value. If the negative number has a greater absolute value, the sum is negative. If the positive number has a greater absolute value the sum is positive. If the absolute values are equal, the sum is zero.
How can you decide if the difference of two numbers is positive negative or zero without actually calculating the difference?
You can do this by inspection. If the second number is smaller than the first, their difference is positive. If the second number is greater than the first, then their difference is negative. If the second number is the same as the first number, then their difference is zero.

What happens when you use the Sum function and in the range of cells you find negative numbers?
It will still perform the calculation. The SUM function can deal with positive and negative numbers and it will deal with negative numbers correctly. So there will be no problems or errors if there are negative numbers amongst the numbers in the range of cells that it is calculating.
Why does a positive plus positive equals negative?
Actually it doesn't. Add two positive numbers, and you always get a positive result.
Without actually calculating the answer how can you decide if the difference of two numbers is positive negative or zero?
