Question

adding integers
if both integers are negative, then their sum is
always positive
always negative
can be positive or
can be negative.

Explanation:

Step1: Recall integer addition rule

For adding two negative integers, e.g., $-a + (-b)$ (where $a,b>0$), it's equivalent to $-(a + b)$.

Step2: Analyze the result

Since $a$ and $b$ are positive, $a + b$ is positive, so $-(a + b)$ is negative. Thus, sum of two negative integers is always negative.

Answer:

always negative
