### Theory:

While the addition of $$2$$ integers depends upon the sign of the two or more integers, the answer can change.

Addition of integers:
If the given numbers consist of the same sign or different sign, add those numbers and give the larger number sign to the result.
Example:
1. In the above example, ($$-3$$) and ($$-4$$) are added both the integers have a negative sign, hence answer is $$-7$$.

2. $$(-6) + (-5) = -11$$

3. $$10 + 12 = 22$$

4. $$(-32) + (-14) = -48$$

5. $$90 + 10 = 100$$
