Obtain an estimate for the following computation by rounding the numbers so that the resulting arithmetic can easily be performed by hand or in your head. Then, use a calculator to perform the computation. How reasonable is your estimate when compared to the actual answer? \( 33.31-14.451 \) An estimate of the difference is \( \square \). (Type a whole number.)

To estimate the difference, you can round the numbers. Round \( 33.31 \) to \( 33 \) and \( 14.451 \) to \( 14 \). Now, performing the subtraction gives you \( 33 - 14 = 19 \). Using a calculator to find the exact answer for \( 33.31 - 14.451 \), you get approximately \( 18.859 \). Comparing your estimate of \( 19 \) to the actual answer shows that your estimation is quite reasonable since it is very close to the actual value.
