[tex] \frac{1}{8} - \frac{2}{ - 3} - \frac{1}{4} - ( \frac{ - 2}{ - 3} )[/tex]

[tex] = \frac{1}{8} - ( - \frac{2}{3} ) - \frac{1}{4} - ( + \frac{2}{3} )[/tex]

[tex] = \frac{1}{8} + \frac{2}{3} - \frac{1}{4} - \frac{2}{3} [/tex]

[tex] = \frac{1}{8} - \frac{1}{4} [/tex]

[tex] = \frac{1}{8} - \frac{2}{8} [/tex]

[tex] = \frac{1 - 2}{8} [/tex]

[tex] = \frac{ - 1}{8} [/tex]

[tex] = - \frac{1}{8} [/tex]

[tex]\it \dfrac{1}{8}-\dfrac{2}{-3}-\dfrac{1}{4}-\dfrac{-2}{-3}= \dfrac{1}{8}+\dfrac{2}{3}-\dfrac{1}{4}-\dfrac{2}{3} =\dfrac{1}{8}-\dfrac{^{2)}1}{\ 4}=\dfrac{1}{8}-\dfrac{2}{8} =-\dfrac{1}{8}[/tex]
