1. \( \begin{array}{r}57 \\ \times \quad 14 \\ \hline\end{array} \)

To multiply \( 57 \) by \( 14 \), you can break it down using the distributive property. First, multiply \( 57 \) by \( 10 \) (which gives \( 570 \)) and then by \( 4 \) (which gives \( 228 \)). Now, add those two results together: \( 570 + 228 = 798 \). So, \( 57 \times 14 = 798 \)! When multiplying two-digit numbers, it's often helpful to stack them and use long multiplication. Write \( 57 \) under \( 14 \) and multiply \( 57 \) by each digit of \( 14 \), starting with \( 4 \) and moving to \( 1 \) (considering place values). This step-by-step method helps you avoid mistakes and keeps your calculations organized.
