To solve the expression \(9 + (18 + 5) \cdot 2 - 22 \div 2\), we follow the order of operations (parentheses, exponents, multiplication and division from left to right, addition and subtraction from left to right).
Let's break it down step by step:
1. Solve the parentheses:
\[
18 + 5 = 23
\]
2. Substitute back into the expression:
\[
9 + 23 \cdot 2 - 22 \div 2
\]
3. Now, perform the multiplication and division:
- Multiplication:
\[
23 \cdot 2 = 46
\]
- Division:
\[
22 \div 2 = 11
\]
4. Substitute these results back into the expression:
\[
9 + 46 - 11
\]
5. Now, perform addition and subtraction from left to right:
- Addition:
\[
9 + 46 = 55
\]
- Subtraction:
\[
55 - 11 = 44
\]
The final result is \(44\).
