14-7-9+8-1+10

解答

14 - 7 - 9 + 8 - 1 + 10

15

求解步骤

14 - 7 - 9 + 8 - 1 + 10

遵循 PEMDAS 运算顺序

加减（左右）

14 - 7 = 7

= 7 - 9 + 8 - 1 + 10

7 - 9 = - 2

= - 2 + 8 - 1 + 10

- 2 + 8 = 6

= 6 - 1 + 10

6 - 1 = 5

= 5 + 10

5 + 10 = 15

= 15

数字行

= 15

16 \div 2 \cdot 4 - 3

50 - 32 \div 4 \times 2 + 21

(3^{5} + 4^{2}) - [(6^{3} - 1) \div 5]

\frac{5 - ( - 3 )}{- 2 - 2}

(6 \times 2^{3}) + 13 - 69 + 3
