To calculate \( 70 \times 55 \), you can break it down into simpler calculations using an array approach.
1. Rewrite the numbers:
- Think of \( 70 \) as \( 70 = 70 \times 1 \).
- Think of \( 55 \) as \( 55 = 50 + 5 \).
2. Set up the array:
- Create an array with \( 70 \) rows and \( 55 \) columns, or you can think of it as a grid with rows of \( 70 \) and adding values according to \( 50 \) and \( 5 \).
3. Now calculate it step by step:
\[
70 \times 55 = 70 \times (50 + 5)
\]
\[
= (70 \times 50) + (70 \times 5)
\]
\[
= 3500 + 350
\]
\[
= 3850
\]
Thus, \( 70 \times 55 = 3850 \).
