Evaluate the expression: 23 - [6 + {8 - (9 - 6)}]

Option 1: 18
Option 2: 21
Option 3: 25
Option 4: 27

Answer 1

To evaluate the expression 23 - [6 + {8 - (9 - 6)}], simplify the parentheses first. The final result is 12, not one of the given options.

Step-by-step explanation:

To evaluate the expression 23 - [6 + {8 - (9 - 6)}], we must start by simplifying the parentheses first. Inside the innermost parentheses, 9 - 6 equals 3.

Now, we can move to the next set of parentheses, {8 - 3}, which equals 5.

Finally, we can simplify the expression inside the square brackets, 6 + 5, which equals 11. Plugging this value back into the original expression, we have 23 - 11, which gives us a final result of 12. Therefore, none of the given options are correct.
