We follow the order of operations (PEMDAS) which means we first solve any expressions inside parentheses, then exponents, then multiplication and division (from left to right), and finally addition and subtraction (from left to right). 
2 + (20 ·23) - 12 
= 2 + 460 - 12 
= 450, therefore the answer is choice letter D. To evaluate the expression, we need to follow the order of operations: 
1. First, we perform the multiplication inside the parentheses: 20 · 23 = 460
2. Next, we add 2 and subtract 12: 2 + 460 - 12 = 450
Therefore, the correct answer is D) 450.
