解答ステップ

- \frac{1}{3} (2) - \frac{3 - 4 ( 2 )}{2}

規則を適用する:

(a) = a

(2) = 2

= - \frac{1}{3} \cdot 2 - \frac{3 - 4 \cdot 2}{2}

- \frac{1}{3} \cdot 2 = - \frac{2}{3}

\frac{3 - 4 \cdot 2}{2} = - \frac{5}{2}

= - \frac{2}{3} - (- \frac{5}{2})

- \frac{2}{3} - (- \frac{5}{2}) = \frac{11}{6}

= \frac{11}{6}
