Question: Add.
┌──────────────────────────────┐
│ −5 + 5 = □ │
│ −4 + (−3) = □ │
└──────────────────────────────┘
1. **State the problem:** We need to find the sums of $-5 + 5$ and $-4 + (-3)$.
2. **Recall the addition rules for integers:** Adding a positive and its negative counterpart results in zero. Adding two negative numbers results in a more negative number by adding their absolute values.
3. **Calculate $-5 + 5$:**
$$-5 + 5 = 0$$
Because $5$ is the additive inverse of $-5$, their sum is zero.
4. **Calculate $-4 + (-3)$:**
$$-4 + (-3) = -(4 + 3) = -7$$
Adding two negative numbers means adding their absolute values and keeping the negative sign.
**Final answers:**
$-5 + 5 = 0$
$-4 + (-3) = -7$
