Let’s break this down in a fun way! First, we take the multiplication part: \( -10 \times 2 = -20 \). Now, we can substitute that back into the equation: \( -20 + 9 - 12 \). Following the order of operations, we combine the numbers step-by-step. Adding \( -20 + 9 \) gives us \( -11 \), and then we subtract \( 12 \) to get \( -23 \). So, the final answer is \( -23 \)! Remember to keep an eye on those negative signs; they can sneak up on you! A common mistake is forgetting to combine like signs correctly. Always double-check your addition or subtraction, especially with negatives. Happy calculating!
