1. The problem is to simplify the expression $-3 + 1 - (-2)$.\n\n2. Recall that subtracting a negative number is the same as adding its positive counterpart. So, $- (-2) = +2$.\n\n3. Rewrite the expression using this rule: $$-3 + 1 + 2$$\n\n4. Now, perform the addition step-by-step: $$(-3 + 1) + 2 = -2 + 2$$\n\n5. Simplify the remaining terms: $$-2 + 2 = 0$$\n\n6. Therefore, the simplified value of the expression is $0$.
