Answer 1

To calculate \(30 \times 40\), you can break it down as follows:

\[
30 \times 40 = 30 \times (4 \times 10) = (30 \times 4) \times 10
\]

First, calculate \(30 \times 4\):

\[
30 \times 4 = 120
\]

Now, multiply by 10:

\[
120 \times 10 = 1200
\]

So, \(30 \times 40 = 1200\).

The correct response is **1,200**.
