Work: Calculate the value of equation (20+19.0×1.5+18.2×2.0+17.6×6.0+19.7×1.7-(11.2-0.85)×10)×0.38-2×7.3×0.61+(11.2-0.85)×10 .
Question type: Mathematical calculation
Solution:
(20+19.0×1.5+18.2×2.0+17.6×6.0+19.7×1.7-(11.2-0.85)×10)×0.38-2×7.3×0.61+(11.2-0.85)×10
=(20+19.0×1.5+18.2×2.0+17.6×6.0+19.7×1.7-10.35×10)×0.38-2×7.3×0.61+(11.2-0.85)×10
=120.49×0.38-2×7.3×0.61+(11.2-0.85)×10
=120.49×0.38-2×7.3×0.61+10.35×10
=45.7862-2×7.3×0.61+10.35×10
=45.7862-14.6×0.61+10.35×10
=45.7862-8.906+10.35×10
=45.7862-8.906+103.5
=36.8802+103.5
=140.3802
Answer:(20+19.0×1.5+18.2×2.0+17.6×6.0+19.7×1.7-(11.2-0.85)×10)×0.38-2×7.3×0.61+(11.2-0.85)×10=140.3802
