Because by 'adding' a negative number to another negative number, you are making the first number even smaller - or more negative
A negative number means to take away. Think about in terms of money. If I owe you five dollars, then I have negative five dollars (-5). If I borrow ten more, then I owe you additional (+) ten dollars (-10). You would then add them together to figure out how much is owed. Five dollars plus ten dollars is fifteen dollars (-5 + -10 = -15).
Or you can think about it this way: two negative numbers added are always negative for the same reasons as when you add positive numbers, their sum is always positive. You get further away from zero, just in opposite directions.</P>

Why does two negative numbers equal a positive?
They do not always. The sum of two negative numbers is negative.
Is the sum of two negative numbers positive or negative?
The sum of two negative numbers is going to sum up to a negative number EX:-2+-5=-7
Is the sum of two opposite integers always positive?
Yes, the sum of two negative integers is always negative.
When is the sum of two negative mixed numbers an integers?
When the sum of the negatives is an integer is when the sum is a whole number
Is the sum of 2 negative always energers negative?
The sum of two negatives is always negative. Not sure what "energers" is, though!
Why does two negative numbers equal a positive?
They do not always. The sum of two negative numbers is negative.
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.
The sum of two numbers is always greater than either of the two numbers?
Not true if either of the numbers is negative.
When adding two negative rational numbers the sum will be negative sometimes never always?
Never.
What type of numbers is the sum of two negative numbers?
They will be negative numbers as for example -5+(-7) = -12
Is the sum of two negative numbers positive or negative?
The sum of two negative numbers is going to sum up to a negative number EX:-2+-5=-7
Is sum of two negative integers always negative and why?
The sum of two negative integers is always negative due to the commutative and associatve property. In other words, summing or adding two negative numbers results in a larger scalar negative number. ex -1 + -1 = -2
The Sum of 2 negative integers is always negative?
the sum of two negative integers is ALWAYS negative
Is the sum of two negative integers always negative?

Is the sum of two opposite integers always positive?
Yes, the sum of two negative integers is always negative.
The sum of two numbers is greater than either number?
The sum of two numbers will almost always be greater than either number. The only exception would be when dealing with two negative numbers.
When is the sum of two negative mixed numbers an integers?
When the sum of the negatives is an integer is when the sum is a whole number
