-14+9× 12\div 36-15+13

解答

- 14 + 9 \times 12 \div 36 - 15 + 13

- 13

求解步骤

- 14 + 9 \times 12 \div 36 - 15 + 13

遵循 PEMDAS 运算顺序

乘除（左右）

9 \times 12 \div 36 : 3

9 \times 12 \div 36

9 \times 12 = 108

= 108 \div 36

108 \div 36 = 3

= 3

= - 14 + 3 - 15 + 13

加减（左右）

- 14 + 3 - 15 + 13 : - 13

- 14 + 3 - 15 + 13

- 14 + 3 = - 11

= - 11 - 15 + 13

- 11 - 15 = - 26

= - 26 + 13

- 26 + 13 = - 13

= - 13

= - 13

\frac{5}{6} (15) + \frac{15}{6}

5 - \frac{5}{7} \div \frac{9}{2}

8 - 9 - 2

- 3 (- 1)^{2} - 6 (- 1)

[6 + (4 \times 3)] - [15 - 9]
