+2-1-6+4

解答

+ 2 - 1 - 6 + 4

- 1

求解步骤

2 - 1 - 6 + 4

遵循 PEMDAS 运算顺序

加减（左右）

2 - 1 = 1

= 1 - 6 + 4

1 - 6 = - 5

= - 5 + 4

- 5 + 4 = - 1

= - 1

数字行

= - 1

(1 \frac{1}{3} - 2) \times 6

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

15 \times 37 + 15 \times 63

\frac{2}{3} + (\frac{1}{2} - \frac{5}{4})

- ((- 8 \div 2) + (4 \times (- 24)) \div (- 3 + (- 1)))
