48.3×3.7-48.3—48.3×1.7=?(要简算)

48.3×3.7-48.3—48.3×1.7=?(要简算)
48.3*3.7-48.3-48.3*1.7
=48.3*3.7-48.3*1-48.3*1.7
=48.3*3.7-(1+1.7)*48.3
=48.3*3.7-48.3*2.7
=48.3*(3.7-2.7)
=48.3*1
=48.3

48.3×3.7-48.3-48.3×1.7
=48.3×(3.7-1-1.7)
=48.3×1
=48.3

48.3×3.7-48.3—48.3×1.7=48.3×(3.7-1-1.7)=48.3

48.3×3.7-48.3-48.3×1.7=48.3×(3.7-1-1.7)=48.3×1=48.3

=48.3(3.7-1-1.7)=48.3

48.3×3.7-48.3—48.3×1.7
=48.3×(3.7-1-1.7)
=48.3

48.3*3.7-48.3-48.3*1.7
=48.3*3.7-48.3*1-48.3*1.7
=48.3*3.7-(1+1.7)*48.3
=48.3*3.7-48.3*2.7
=48.3*(3.7-2.7)
=48.3
