2500-1200-700-350

解答

2500 - 1200 - 700 - 350

250

求解步骤

2500 - 1200 - 700 - 350

遵循 PEMDAS 运算顺序

加减（左右）

2500 - 1200 = 1300

= 1300 - 700 - 350

1300 - 700 = 600

= 600 - 350

600 - 350 = 250

= 250

4 + (- 7) + 9 + (- 1) + 6 + (- 8) + 3 + (- 20)

\frac{1}{( - 1 ) ^{2} + 1}

(4/3) + (5/3) + (8/3)

[9 + (15 \div 5)] 2^{3} - 4

6 \div 2 \cdot (2 + 1)
