Definition: Adding decimals, Write the decimals so that the decimal points line up vertically. Add as with whole numbers. Place the decimal point in the sum so that it lines up vertically with the decimal points in the problem. Subtracting decimals, Write the decimals so that the decimal points line up vertically. Subtract as with whole numbers. Place the decimal point in the difference so that it lines up vertically with the decimal points in the problem. Calculation: \(\displaystyle{0.064}-{10.2}\) The above expression can be written as \(\displaystyle-{10.2}+{0.064}\) 10.2 has 2 whole value. 0.064 has 1 whole value. So, add 0 to 0.0064 at the front. The number becomes 00.064 0.064 has 3 decimal places 10.2 has 1 decimal places So, add 0s to 10.2 at the end. The number becomes 10.200 Based on the definition, \(\displaystyle-{10.200}+{00.064}=-{10.136}\) Answer: \(\displaystyle{0.064}-{10.2}=-{10.136}\)

Consider the quantity\(a^{2}\ -\ b^{2}\) where a and b are real numbers.
(a) Under what conditions should one expect an unusually large relative error in the computed value of \(a^{2}\ -\ b^{2}\) when this expression is evaluated in finite precision arithmetic?
(b)cWs 4-digit (decimal) rounding arithmetic to evaluate both \(a^{2}\ -\ b^{2}\ and\ (a\ +\ b)(a\ -\ b)\ with\ a\ = 995.1\ and\ b = 995.0.\) Calculate th relative error in each result.
(c) The expression \((a\ +\ b)(a\ -\ b)\ is\ algebraically\ equivalent\ to\ a^{2}\ -\ b^{2},\) but it is a more accurate way to calculate this quantity if both a and b have exact floating point representations. Why?
