Work: Calculate the value of equation (30+17.5×2.5+16.8×1.5+19.3×7.0+17.8×1.5-(12.5-0.85)×10)×0.33-2×6.7×0.57+(12.5-0.85)×10 .
Question type: Mathematical calculation
Solution:
(30+17.5×2.5+16.8×1.5+19.3×7.0+17.8×1.5-(12.5-0.85)×10)×0.33-2×6.7×0.57+(12.5-0.85)×10
=(30+17.5×2.5+16.8×1.5+19.3×7.0+17.8×1.5-11.65×10)×0.33-2×6.7×0.57+(12.5-0.85)×10
=144.25×0.33-2×6.7×0.57+(12.5-0.85)×10
=144.25×0.33-2×6.7×0.57+11.65×10
=47.6025-2×6.7×0.57+11.65×10
=47.6025-13.4×0.57+11.65×10
=47.6025-7.638+11.65×10
=47.6025-7.638+116.5
=39.9645+116.5
=156.4645
Answer:(30+17.5×2.5+16.8×1.5+19.3×7.0+17.8×1.5-(12.5-0.85)×10)×0.33-2×6.7×0.57+(12.5-0.85)×10=156.4645
