The final answer is 7.
Solution
Let's solve the expression step by step:
\[
[12 - (15 - 7)] + 3
\]
1. **Calculate the expression inside the innermost parentheses:**
\[
15 - 7 = 8
\]
So, the expression becomes:
\[
[12 - 8] + 3
\]
2. **Subtract inside the brackets:**
\[
12 - 8 = 4
\]
Now, the expression is:
\[
4 + 3
\]
3. **Add the remaining numbers:**
\[
4 + 3 = 7
\]
**Final Answer:**
\[
[12 - (15 - 7)] + 3 = 7
\]
