簡約-(44)/(-2)+(12)/((-7+3))+12

解

簡約

- \frac{44}{- 2} + \frac{12}{( - 7 + 3 )} + 12

31

解答ステップ

- \frac{44}{- 2} + \frac{12}{- 7 + 3} + 12

- \frac{44}{- 2} = 22

- \frac{44}{- 2}

数を割る:

\frac{44}{- 2} = - 22

= - (- 22)

規則を適用する:

- (- a) = a

- (- 22) = 22

= 22

\frac{12}{- 7 + 3} = - 3

\frac{12}{- 7 + 3}

数を足す:

- 7 + 3 = - 4

= \frac{12}{- 4}

数を割る:

\frac{12}{- 4} = - 3

= - 3

= 22 - 3 + 12

数を足す:

22 - 3 + 12 = 31

= 31
