Question: Add: $-3 + (-2)$
1. **State the problem:** We need to add the two rational numbers $-3$ and $-2$.
2. **Recall the rule for adding negative numbers:** When adding two negative numbers, you add their absolute values and keep the negative sign.
3. **Apply the rule:**
$$-3 + (-2) = -(3 + 2)$$
4. **Calculate the sum inside the parentheses:**
$$3 + 2 = 5$$
5. **Write the final answer:**
$$-3 + (-2) = -5$$
So, the sum of $-3$ and $-2$ is $-5$.
