Here's how to solve the expression step-by-step using the order of operations (BODMAS/PEMDAS): The expression is: [-45 + 7 × 23 - (247 ÷ 13) - 11] ÷ 2 Step 1: Evaluate the expression inside the innermost parentheses. (247 ÷ 13) 247 ÷ 13 = 19 Step 2: Substitute this value back into the square brackets. [-45 + 7 × 23 - 19 - 11] ÷ 2 Step 3: Inside the square brackets, perform the multiplication. 7 × 23 = 161 Step 4: Substitute this value back into the square brackets. [-45 + 161 - 19 - 11] ÷ 2 Step 5: Perform the additions and subtractions from left to right inside the square brackets. -45 + 161 = 116 116 - 19 = 97 97 - 11 = 86 So, the value inside the square brackets is 86. Step 6: Substitute this value back into the main expression and perform the final division. 86 ÷ 2 86 ÷ 2 = 43 The final answer is 43.
