Answer
\[
\square = 7
\]
Solution
Let's solve the expression step by step.
1. Start with the original expression:
\[
[4 + (8 - 1)] - 9
\]
2. Calculate the value inside the parentheses:
\[
8 - 1 = 7
\]
3. Substitute this value back into the expression:
\[
[4 + 7] - 9
\]
4. Now, calculate \(4 + 7\):
\[
4 + 7 = 11
\]
5. Substitute this value back into the expression:
\[
11 - 9
\]
6. Finally, calculate \(11 - 9\):
\[
11 - 9 = 2
\]
Now, let's relate this to the equation you provided:
\[
[4 + \square] - 9 = \square - 9
\]
From our calculations, we found that:
\[
[4 + 7] - 9 = 2
\]
Thus, we can conclude that:
\[
\square = 7
\]
So, the final answer is:
\[
\square = 7
\]

Simplify this solution Beyond the Answer
When we solve the expression \( 4 + (8 - 1) \), we first calculate the value inside the parentheses: \( 8 - 1 = 7 \). So, the expression simplifies to \( 4 + 7 - 9 \). The value of \( 4 + 7 \) is \( 11 \), and then \( 11 - 9 = 2 \). Hence, the original equation can be rewritten to show that \(\square = 11\) in this context. If we label the box as \(\square\), it could lead to a fun little riddle! You can think of the box as a treasure chest waiting to reveal its contents. In this case, the value inside our chest (the box) turns out to be 11, giving us the key to solving for the rest of the puzzle. How cool is that?
