-1+2+3-6+4\div 2-1+1

解答

- 1 + 2 + 3 - 6 + 4 \div 2 - 1 + 1

0

求解步骤

- 1 + 2 + 3 - 6 + 4 \div 2 - 1 + 1

遵循 PEMDAS 运算顺序

乘除（左右）

4 \div 2 : 2

4 \div 2

4 \div 2 = 2

= 2

= - 1 + 2 + 3 - 6 + 2 - 1 + 1

加减（左右）

- 1 + 2 + 3 - 6 + 2 - 1 + 1 : 0

- 1 + 2 + 3 - 6 + 2 - 1 + 1

- 1 + 2 = 1

= 1 + 3 - 6 + 2 - 1 + 1

1 + 3 = 4

= 4 - 6 + 2 - 1 + 1

4 - 6 = - 2

= - 2 + 2 - 1 + 1

- 2 + 2 = 0

= 0 - 1 + 1

0 - 1 = - 1

= - 1 + 1

- 1 + 1 = 0

= 0

= 0
