1^6-8+13+12+6+3

解答

1^{6} - 8 + 13 + 12 + 6 + 3

27

求解步骤

1^{6} - 8 + 13 + 12 + 6 + 3

遵循 PEMDAS 运算顺序

计算幂值

1^{6} : 1

1^{6}

1^{6} = 1

= 1

= 1 - 8 + 13 + 12 + 6 + 3

加减（左右）

1 - 8 + 13 + 12 + 6 + 3 : 27

1 - 8 + 13 + 12 + 6 + 3

1 - 8 = - 7

= - 7 + 13 + 12 + 6 + 3

- 7 + 13 = 6

= 6 + 12 + 6 + 3

6 + 12 = 18

= 18 + 6 + 3

18 + 6 = 24

= 24 + 3

24 + 3 = 27

= 27

= 27

24 \div 8 \times (52 \div 9)

- 3 (42 + 52 - (71 - 3)) + 14

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

4 \div 5 + 1 \div 6 - 2 \div 31 \div 9

- 30 + 10 \times 5 + 7 - 15
