What is estimation?

We sometimes think of an estimate as just a guess. In mathematics, it means something a bit more useful - an educated guess. Even though the answer isn't exactly known, with estimation, you can not only give a good approximation, but also, you can give an idea of how close your estimate is to the 'true' answer.

For example, suppose you want to buy some music CDs for a gift. You have \$50 to spend and you know CDs range in price from about 8 to 12 dollars. What's a good estimate for how many you can get? Well, if you get them all at \$8, you can get 6.

On the other hand, if you just buy the more expensive CDs, you could only buy 4. In this example, your estimate would be, "I can buy at least 4, but no more than 6."

You don't have an exact answer, but you have a realistic range - an educated guess.
