Dad and Mingming are playing a game. Dad says: "Think of a number and remember it, but don't say it out loud. Then add 90 to this number, subtract 27, subtract the number you thought of, then multiply by 11, and finally divide by 3. I can guess the answer. The final answer is $\qquad$"
Analysis: The test point is calculation.
First, add 90 to this number, then subtract 27 and subtract the number you thought of, so the number has already been subtracted, so the final result has nothing to do with the number you thought of, thus the final answer is $(90-27) \times 11 \div 3=231$.
