Certainly! Let's calculate \( 14,\!815 \times 38 \) step by step using the standard multiplication method. \[ \begin{array}{r} \phantom{0}14,\!815 \\ \times \phantom{0}38 \\ \hline \phantom{0}118,\!520 \quad \text{(This is } 14,\!815 \times 8\text{)} \\ +444,\!450 \quad \text{(This is } 14,\!815 \times 30\text{)} \\ \hline \underline{562,\!970} \\ \end{array} \] **Detailed Steps:** 1. **Multiply by the Ones Place (8):** \[ 14,\!815 \times 8 = 118,\!520 \] 2. **Multiply by the Tens Place (30):** \[ 14,\!815 \times 30 = 444,\!450 \] *(Note: 30 is \( 3 \times 10 \), so you can multiply by 3 and then add a zero at the end.)* 3. **Add the Two Results:** \[ 118,\!520 + 444,\!450 = 562,\!970 \] **Final Answer:** \[ 14,\!815 \times 38 = 562,\!970 \]
