\[ \begin{aligned} 2 \times 3 & =(50+2) \times 3 \\ & =(50 \times 3)+(2 \times 3) \\ & =150+6 \\ & =156 \end{aligned} \] \[ \begin{aligned} 225 \times 3 & =(200+20+5) \times 3 \\ & =(200 \times 3)+(20 \times 3)+(5 \times 3) \\ & =600+60+15 \\ & =675 \end{aligned} \] 57

          \[
\begin{aligned}
2 \times 3 & =(50+2) \times 3 \\
& =(50 \times 3)+(2 \times 3) \\
& =150+6 \\
& =156
\end{aligned}
\]
\[
\begin{aligned}
225 \times 3 & =(200+20+5) \times 3 \\
& =(200 \times 3)+(20 \times 3)+(5 \times 3) \\
& =600+60+15 \\
& =675
\end{aligned}

2 × 3 =(50+2) × 3
=(50 × 3)+(2 × 3)
=150+6
=156

225 × 3 =(200+20+5) × 3
=(200 × 3)+(20 × 3)+(5 × 3)
=600+60+15
=675
