$= > if \: x = \frac{1}{10} \: \: and \: \: y = \frac{9}{5} \\ \\ (x + y) + (x - y) \\ \\ = > ( \frac{1}{10} + \frac{9}{5} ) + ( \frac{1}{10} - \frac{9}{5} ) \\ \\ = > (\frac{1 + 18}{10}) + ( \frac{1 - 18}{10} ) \\ \\ = > \frac{19}{10} + ( \frac{ - 17}{10} ) \\ \\ = > \frac{19 - 17}{10} \\ \\ = > \frac{2}{5} \\ \\ = > \frac{1}{5} \\ \\ = > 0.2$
