问题描述:
0.1 0.2 0.3 0.4 0.5 在中间加运算符号分别等于0.1 0
答
0.1+0.2-0.3+0.4-0.5=0
0.1-0.2+0.3+0.4-0.5=0.1
答
(1)0.1-0.2+0.3+0.4-0.5=0.1
(2)0.1+0.2-0.3-0.4+0.5=0.1
(3)-0.1-0.2+0.3-0.4+0.5=0.1
(1)(0.1+0.2-0.3)*0.4*0.5=0
(2)(0.1+0.4-0.5)*0.2*0.3=0
(3)(0.2+0.3-0.5)*0.1*0.4=0
希望能帮上忙~
答
0.1-0.2+0.3+0.4-0.5=0.1
(0.1+0.2)/0.3 -0.4-0.5=0.1
0.1+0.2-0.3-0.4+0.5=0.1
(0.1+0.2-0.3)/(0.4+0.5)=0
(0.1+0.2-0.3)/(0.4-0.5)=0
