计算; [ -1-(1-2分之1)÷3}÷3}÷(-3-2×2).
计算; [ -1-(1-2分之1)÷3}÷3}÷(-3-2×2).

计算; [ -1-(1-2分之1)÷3}÷3}÷(-3-2×2).
原式 ={[-1-0.5÷3]÷3}÷(-3-4)
= [ ( -1-1/6)÷3]÷(-7)
= ( -7/6÷3)÷(-7)
= -7/18÷(-7)
= 1/18
注:/是分数线.1/2即为二分之一

{ [ -1-(1-2分之1)÷3]÷3}÷(-3-2×2)
={ [ -1-2分之1÷3]÷3}÷(-3-4)
={ [ -1--6分之1]÷3}÷(-7)
={-6分之7÷3}÷(-7)
=-18分之7÷(-7)
=18分之1

[ -1-(1-2分之1)÷3}÷3}÷(-3-2×2).
= [ -1-1/6}÷3}÷(-3-2×2).
= [ -7/18}÷(--7)
=1/18

((-1-1/2)/3)/3/(-7)
