Why should we estimate before solving a problem?

We should estimate before solving a problem to make sure our answer is close to the real answer.

Here's a simple problem.

Suppose we want to find wnat a 6% tax on a $10 purchase would be. When you do the math, the answer depends upon where you place the decimal point when you multiply .06 x $10.

You need to estimate what is a reasonable tax on a $10 purchase -- 6 cents? 60 cents? 6 dollars?
