For example, 5 is the "inverse" of -5.
And -7 is the "inverse" for 7.
Its impossible if they are both absolute value with different signs. If they have different signs one would be absolute value and one would be negative value.
It is impossible. The absolute value is always positive.
If you are talking about same numbers but different signs then there are a lot. such a l-4l = l4l because they are the same amount of space to the zero.
opposites, additive inverses
Subtract the absolute value of the smaller number from the absolute value of the larger number. The answer will have the sign of the larger numbers.

No. The sign you will use is going to be the sign with the greater absolute value.
-1Another opinionIf this question in asking about so-called "absolute numbers" - which are numbers without any signs (+ or -) - then there is no whole number predecessor to zero.
Adding two numbers with different signs means subtracting the two absolute integers (without sign) and vice versa.

Mutual negatives or additive inverses.
You add all the numbers with + signs and subtract all that have minus signs.
Then you are adding two rational numbers with different signs! No big deal!
Consider the absolute values (the numerical values ignoring the signs) of the two numbers. If these are equal then the sum is equal; otherwise the sum takes the sign of which ever number has the larger absolute value.
