Never. The sum of two negative numbers is a negative number with a value less than either of them, e.g. (-1) + (-2) = (-3)
Adding two negative numbers is the same as adding their positive absolute values, and expressing the sum as a negative.
If the two negative numbers are the same, and you subtract one from the other, the result is 0.
e.g. (-2) - (-2) is the same as (-2) + 2 , which equals 0.

What are two numbers that are equal distance from zero on a number line called?
For two numbers to be equidistant from zero, one must be the negative of the other. As one is the negative of the other, it is the additive inverse of that number. The sum of an number and its additive inverse is zero.
What are two numbers the same distance from zero on the number line?
Numbers the same distance from zero (linearly) have the same "absolute value" whether positive or negative.
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.
The product of two numbers that are less than zero is also less than zero.?
No. The product of two negative numbers is positive.
When is the product of two negative real numbers always greater than zero?
Whenever you multiply two negative real numbers.
