To solve the expression \( 12 + \frac{1}{2} \times 48 \times 18 \) step by step, we will follow the order of operations (multiplication before addition).
Step 1: Calculate \(\frac{1}{2} \times 48\)
\[ \frac{1}{2} \times 48 = 24 \]
Step 2: Multiply the result by 18
\[ 24 \times 18 \] To calculate this, you can break it down as follows: \[ 24 \times 18 = 432 \]
Step 3: Add 12 to the result from Step 2
\[ 12 + 432 = 444 \]
Final Result
So, \( 12 + \frac{1}{2} \times 48 \times 18 = 444 \).
