0.32*6.7+3.2*0.43-0.32简便计算0.32*6.7+3.2*0.43-0.32简便计算0.32*6.7+3.2*0.43-0.32简便计算=0.32x6.7+0.32x4.3-0.3
0.32*6.7+3.2*0.43-0.32 简便计算
0.32*6.7+3.2*0.43-0.32 简便计算
0.32*6.7+3.2*0.43-0.32 简便计算
=0.32x6.7+0.32x4.3-0.32
=0.32x(6.7+4.3-1)
=0.32x10
=3.2
谢谢o(︶︿︶)o
3.2
把0.32提出来后合并计算
简化后为0.32*(6.7+4.3-1)=3.2
3.2
=3.2x0.67+3.2x0.43-3.2x0.1=(0.67+0.43+0.1)x3.2=3.84
