Let’s tackle this step by step by following the order of operations (PEMDAS/BODMAS). 1. Division first: \( 14 \div -2 = -7 \) 2. Next, multiply: \( -7 \times 10 = -70 \) 3. Now, proceed with subtraction: \( -70 - 20 = -90 \) 4. Finally, add: \( -90 + 11 = -79 \) So, the final result is \( -79 \). Keep practicing your order of operations, and you'll become a math wizard in no time!
