To solve the expression "2 + [3 × (4 - 1)]", we start by addressing the operation inside the parentheses, which is 4 - 1. This simplifies to 3. Next, we multiply this result by 3, giving us 3 × 3 = 9. Now, we add this product to 2. So, we calculate 2 + 9, which equals 11. Therefore, the final result of the expression "2 + [3 × (4 - 1)]" is 11.
