\frac{5 + ( - 6 ) 3}{3}

\frac{5}{3} - 23

十进制

- 1.79743 \dots

求解步骤

\frac{5 + ( - 6 ) 3}{3}

去除括号:

(- a) = - a

= \frac{5 - 6 3}{3}

使用分式法则:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{5 - 6 3}{3} = \frac{5}{3} - \frac{6 3}{3}

= \frac{5}{3} - \frac{6 3}{3}

数字相除:

\frac{6}{3} = 2

= \frac{5}{3} - 23
