52.2 is close to 50, and 39.7 is close to 40. If you multiply 50*40, what do you get?

148.3 is close to what? 150, right?
232.51 is close to what? 230, right? What happens when you multiply those two estimates?
Use Google to check your multiplication:
1. Go to http://www.google.com
2. Enter <b>50*40</b> and press Enter.
3. Did you get the right answer?
4. Try it again for the second problem.
