求解步骤

7 + (14 - (15 + (4 + 10) + (10 - 4) - 10) + 2) + 4

遵循 PEMDAS 运算顺序

计算括号内的值

(14 - (15 + (4 + 10) + (10 - 4) - 10) + 2) : - 9

14 - (15 + (4 + 10) + (10 - 4) - 10) + 2

计算括号内的值

(15 + (4 + 10) + (10 - 4) - 10) : 25

15 + (4 + 10) + (10 - 4) - 10

计算括号内的值

(4 + 10) : 14

4 + 10

4 + 10 = 14

= 14

= 15 + 14 + (10 - 4) - 10

计算括号内的值

(10 - 4) : 6

10 - 4

10 - 4 = 6

= 6

= 15 + 14 + 6 - 10

加减（左右）

15 + 14 + 6 - 10 : 25

15 + 14 + 6 - 10

15 + 14 = 29

= 29 + 6 - 10

29 + 6 = 35

= 35 - 10

35 - 10 = 25

= 25

= 25

= 14 - 25 + 2

加减（左右）

14 - 25 + 2 : - 9

14 - 25 + 2

14 - 25 = - 11

= - 11 + 2

- 11 + 2 = - 9

= - 9

= - 9

= 7 - 9 + 4

加减（左右）

7 - 9 + 4 : 2

7 - 9 + 4

7 - 9 = - 2

= - 2 + 4

- 2 + 4 = 2

= 2

= 2

9^{10} + 9^{10} + 9^{10}

2 (6) + 3

0^{2} - 40 - 24 + 60

(1 1/9)+(4-2 1/3)

(1 \frac{1}{9}) + (4 - 2 \frac{1}{3})
