1. The problem is to simplify the expression: $$18 + (-11) - 4$$ 2. We use the rule that adding a negative number is the same as subtracting the positive number. So, $$18 + (-11) = 18 - 11$$. 3. Calculate $$18 - 11 = 7$$. 4. Now subtract 4: $$7 - 4 = 3$$. 5. Therefore, the simplified result is $$3$$. The correct answer is 3.
