10.4-9.6×0.35=10.4-(10-0.4)×0.35=10.4-(10×0.35-0.4×0.35)=10.4-(3.5-0.14)=10.4-3.36=7.04
再问：谢了哦！
令0.23+0.34+0.56=a则1+0.23+0.34=1+a-0.560.23+0.34+0.56=a1+0.23+0.34+0.56=1+a0.23+0.34=a-0.56所以原式=a(1+a
2.616+(10.4-1又十三分之七*0.234)/2又七分之六＝2.616＋（10.4－0.252）÷2又7分之6＝2.616＋10.148×20分之7＝2.616＋3.5518＝6.16788又

令A=0.23+0.34=0.57原式=(1+A)*(A+0.65)-(1+A+0.65)*A=A+A2+0.65A+0.65-A-A2-0.65A=0.65
11-(0.23+0.23+4.54)=6
这就是个移项问题(1+0.23+0.34)X(0.23+0.34+0.56)-[(1+0.23+0.34)X(0.23+0.34)+0.56X(0.23+0.34)]=(1+0.23+0.34)X(0
（1+0.23+0.34）*（0.23+034+0.56）-（1+0.23+0.34+0.56）*（0.23+0.34）=（0.23+0.34+0.56）+（0.23+0.34）*（0.23+0.34
25.6-(0.23+5.6)-51.7=25.6-5.6-51.7-0.23=20-51.7-0.23=-31.7-0.23=-31.93
(1+0.23+0.34)*(0.23+0.34+0.65)-(1+0.23+0.34+0.65)*(0.23+0.34)=(1+A)*B-(1+B)A=B+A*B-A-B*A=B-A设长=a宽=b高
=0.23×）0.4×0.5）=0.23×0.2=0.046
设1+0.23+034=a，0.23+0.34=b，那么a-b=1+00.23+0.34-（0.23+0.34）=1．（1+0.23+0.34）×（0.23+0.34+0.56）-（1+0.23+0.
1立方厘米=1毫升1立方分米=1升0.23升=0.23立方分米=230立方厘米0.75立方米=750立方分米=750升125立方厘米=125毫升
11-0.23-0.23-4.54=11-(0.23+0.23+4.54)=11-(0.46+4.54)=11-5=6

设0.12+0.23=x，0.12+0.23+0.34=y．则：（1+0.12+0.23）×（0.12+0.23+0.34）-（1+0.12+0.23+0.34）×（0.12+0.23）=（1+x）y
(1+0.23+0.34)×（0.23+0.34+0.65）-（1+0.23+0.34+0.65）×（0.23+0.34）=(0.23+0.34+0.65)+(0.23+0.34)×(0.23+0.3
