Answer

To solve the expression \( 4 + 16 - 5 + 12 \), we will follow the order of operations, which prioritizes addition and subtraction from left to right.

### Step-by-Step Solution:

1. **Start with the expression**:
\[ 4 + 16 - 5 + 12 \]

2. **Perform the first addition**:
\[ 4 + 16 = 20 \]
Now the expression becomes:
\[ 20 - 5 + 12 \]

3. **Next, perform the subtraction**:
\[ 20 - 5 = 15 \]
Now the expression updates to:
\[ 15 + 12 \]

4. **Finally, perform the last addition**:
\[ 15 + 12 = 27 \]

Thus, the final result of the expression \( 4 + 16 - 5 + 12 \) is:
\[ \boxed{27} \]
