Otrain an estimate for the foliowing 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? \( 32.45-14.189 \) An estimate of the difference is I. (Type a whole number)

Rounding 32.45 to 32 and 14.189 to 14 makes the arithmetic simple. Now, subtracting: 32 - 14 gives you an estimate of 18. Using a calculator, the actual computation \( 32.45 - 14.189 \) equals approximately 18.261. Comparing this to your estimate, it's quite reasonable! Your rounding gave a close approximation that’s only slightly lower than the actual difference. It’s a good reminder that rounding can simplify calculations without straying too far from reality!
