5.19×3.7+3.37×4.18
=(4.18+1.01)×3.7+33.7×0.418
=4.18×3.7+1.01×3.7+33.7×0.418
=0.418×37+1.01×3.7+33.7×0.418
=0.418×(37+33.7)+1.01×3.7
=0.418×70.7+1.01×3.7
=0.418×1.01×70+1.01×3.7
=1.01×(29.26+3.7)
=(1+0.01)×32.96
=32.96+0.3296
=33.2896
=(4.18+1.01)×3.7+33.7×0.418
=4.18×3.7+1.01×3.7+33.7×0.418
=0.418×37+1.01×3.7+33.7×0.418
=0.418×(37+33.7)+1.01×3.7
=0.418×70.7+1.01×3.7
=0.418×1.01×70+1.01×3.7
=1.01×(29.26+3.7)
=(1+0.01)×32.96
=32.96+0.3296
=33.2896

原式=(5+0.19)(4-0.3)+(3+0.37)(4+0.18)=20-1.5+7.6-0.057+12+0.54+1.48+0.0666=33.2896
