0.32×6.7+3.2×0.43-0.32 简算
0.32×6.7+3.2×0.43-0.32 简算

0.32×6.7+3.2×0.43-0.32 简算
0.32*6.7+3.2*0.43-0.32
= 0.32*6.7+0.32*4.3-0.32
= 0.32*(6.7+4.3-1)
= 0.32*10
= 3.2

0.32×6.7+3.2×0.43-0.32=0.32×6.7+0.32×4.3-0.32=0.32×(6.7+4.3-1)=3.2

3.2

0.32×6.7+3.2×0.43-0.32
=0.32×6.7+0.32×4.3-0.32 ×1
=0.32(6.7+4.3-1)
=0.32×10
=3.2
完成!

原式=0.32×6.7+0.32×4.3-0.32×1
=0.32×(6.7+4.3-1)
=0.32×10
=3.2

亲,连这个问题你都问~
=0.32×6.7+0.32×4.3-0.32
=0.32×(6.7+4.3-1)
=3.2
