20

22

24

23

To determine Sam's age using the provided expression, we need to break down the operations step by step.

First, we start with twice 21:

\[ 2 \times 21 = 42 \]

Next, we subtract 7 from this result:

\[ 42 - 7 = 35 \]

Then, we add 11 to the new result:

\[ 35 + 11 = 46 \]

Finally, we divide the total by 2:

\[ 46 \div 2 = 23 \]

Thus, through this series of calculations, we arrive at the final result of 23, which represents Sam's age. This step-by-step method shows how each operation contributes to finding the final answer.
