Answer

To solve the expression \( 48 - 12 \text{ of } 2 + [3 + 17 \times 2] \), we will follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

### Step-by-Step Solution:

1. **Calculate inside the brackets first**:
\[ 17 \times 2 = 34 \]
Now, substitute this back into the expression:
\[ 48 - 12 \text{ of } 2 + [3 + 34] \]

2. **Add the values inside the brackets**:
\[ 3 + 34 = 37 \]
Now, substitute this back into the expression:
\[ 48 - 12 \text{ of } 2 + 37 \]

3. **Calculate \( 12 \text{ of } 2 \)** (which means \( 12 \times 2 \)):
\[ 12 \times 2 = 24 \]
Now, substitute this back into the expression:
\[ 48 - 24 + 37 \]

4. **Perform the subtraction**:
\[ 48 - 24 = 24 \]
Now, substitute this back into the expression:
\[ 24 + 37 \]

5. **Finally, perform the addition**:
\[ 24 + 37 = 61 \]

Thus, the final answer is:
\[ \boxed{61} \]
