If you add a positive number and a negative number, and the positive number is larger (in absolute value) than the negative number, then the sum is positive. For example, 7 + (-5) is the same thing as 7 - 5 which equals 2. Adding a negative number is equivalent to subtracting a positive number. If the two numbers are the same (in absolute value) then the sum is zero. You will be subtracting a number from itself. And finally, if the negative number is larger (in absolute value) than the positive number, then the sum is negative. In other words, you have more negative than positive so you end up with negative. It's pretty simple. An example would be, 3 + (-4) which equals 3 - 4 which is -1.
