additive inverses
Then you are adding two rational numbers with different signs! No big deal!
If the two numbers have different signs, then the result will be negative. If the two numbers have the same signs, the result will be positive. This assumes all the numbers are non-zero.
To add two integers with opposite signs . . . -- Ignore the signs, and write the difference between the two numbers. -- Give it the same sign as the larger original number has.
If two numbers have the same sign, their product is positive. If two numbers have opposite signs, their product is negative. So the answer is 'yes'.

negative
If two numbers have opposite signs then they are at the same distance from zero but on opposite sides of it. Conventionally, positive numbers are to the right of the zero or above it whereas negative numbers are to the left or below.
They are differentone is positive, one is negative
If two numbers have opposite signs, then their product and quotient are both negative.
The value of the quotient of two integers with different signs is the same as if the signs were the same. Because the numbers have different signs, the quotient is negative.
Opposite numbers.
