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)×0.35-2×8.7×0.59+(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)×0.35-2×8.7×0.59+(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)×0.35-2×8.7×0.59+(12.5-0.85)×10
=144.25×0.35-2×8.7×0.59+(12.5-0.85)×10
=144.25×0.35-2×8.7×0.59+11.65×10
=50.4875-2×8.7×0.59+11.65×10
=50.4875-17.4×0.59+11.65×10
=50.4875-10.266+11.65×10
=50.4875-10.266+116.5
=40.2215+116.5
=156.7215
Answer:(30+17.5×2.5+16.8×1.5+19.3×7.0+17.8×1.5-(12.5-0.85)×10)×0.35-2×8.7×0.59+(12.5-0.85)×10=156.7215
