求解步骤

(8 - 3) - 7

遵循 PEMDAS 运算顺序

计算括号内的值

(8 - 3) : 5

8 - 3

8 - 3 = 5

= 5

= 5 - 7

加减（左右）

5 - 7 : - 2

5 - 7

5 - 7 = - 2

= - 2

= - 2

- 3 8^{3} + \frac{5}{8} 8 + \frac{2}{3}

6 + 35 \div 7 (24 \div 6 + 10)

1 + 5 (4 \times 7 + 5 (15 - 4 \times 5)) - 3 (7 - 4)

(3 - 2) + (1 + 3)

- 4 \cdot 0 + 3
