5-(8+3)-6

解答

5 - (8 + 3) - 6

- 12

求解步骤

5 - (8 + 3) - 6

遵循 PEMDAS 运算顺序

计算括号内的值

(8 + 3) : 11

8 + 3

8 + 3 = 11

= 11

= 5 - 11 - 6

加减（左右）

5 - 11 - 6 : - 12

5 - 11 - 6

5 - 11 = - 6

= - 6 - 6

- 6 - 6 = - 12

= - 12

= - 12

18 + 3 (\frac{10}{15})

1^{3} - 1^{2} + 1 - 1

3 - 2 + (1 - 7 - (5 - (2 - 2) - 1) + 1)

(3 + 5)^{2} + (12 \div 4)

750 \div 600 \times 100
