(0.1 + 0.2 - 0.3) * 0.4 = 0
0.1 + 0.2 -0.3 - 0.4 + 0.5 = 0.1
-(0.1 + 0.2)/ 0.3 * (0.4 - 0.5) = 1
(-0.1 - 0.2 + 0.3) * 0.4
觉得不行,还要别的答案也hi我,我现在很忙

0.1-0.2+0.3-(0.4*0.5)=0
0.1+0.2-0.3-(0.4-0.5)=0.1
(0.1/0.2-0.3)/0.4+0.5=1
(0.1/0.2-0.3)/0.4-0.5=1

(0.1+0.2-0.3)*0.4*0.5=0
(0.1+0.2+0.3-0.4)*0.5=0.1
(0.1+0.2+0.3)/0.4-0.5=1
(0.1-0.2-0.3+0.4)*0.5=0
这个肯定对,放心!!!!!!!!!!!!!!
