Estimate, then record the product 837 times 9

To estimate the product of \( 837 \times 9 \), let's round \( 837 \) to the nearest hundred, which is \( 800 \), and multiply:

\[
800 \times 9 = 7200
\]

So, the estimate is approximately \( 7200 \).

Now, let's calculate the exact product:

\[
837 \times 9 = 7533
\]

The exact product is \( 7533 \).
