Same rules as adding whole numbers with different signs.
No.
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.
The numerical value is the same as the quotient of the two positive equivalents but the sign is always negative.
Positive.
