3.75×3.1+7.3×3.75-3.75
=3.1×3.75+7.3×3.75-3.75
=(3.1+7.3)×3.75-3.75
=10.4×3.75-3.75
=(10+0.4)×3.75-3.75
=10×3.75+0.4×3.75-3.75
=37.5+0.4×(3+0.75)-3.75
=37.5+0.4×3+0.4×0.75-3.75
=37.5+1.2+0.4×0.25×3-3.75
=37.5+1.2+0.1×3-3.75
=37.5+1.2+0.3-3.75
=38.7+0.3-(3+0.75)
=39-3-0.75
=36-0.75
=35.25
=3.1×3.75+7.3×3.75-3.75
=(3.1+7.3)×3.75-3.75
=10.4×3.75-3.75
=(10+0.4)×3.75-3.75
=10×3.75+0.4×3.75-3.75
=37.5+0.4×(3+0.75)-3.75
=37.5+0.4×3+0.4×0.75-3.75
=37.5+1.2+0.4×0.25×3-3.75
=37.5+1.2+0.1×3-3.75
=37.5+1.2+0.3-3.75
=38.7+0.3-(3+0.75)
=39-3-0.75
=36-0.75
=35.25
