[1/1 Formula]
    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)×0.36-2×7.4×0.60+(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)×0.36-2×7.4×0.60+(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)×0.36-2×7.4×0.60+(11.2-0.85)×10
        =120.49×0.36-2×7.4×0.60+(11.2-0.85)×10
        =120.49×0.36-2×7.4×0.60+10.35×10
        =43.3764-2×7.4×0.6+10.35×10
        =43.3764-14.8×0.6+10.35×10
        =43.3764-8.88+10.35×10
        =43.3764-8.88+103.5
        =34.4964+103.5
        =137.9964

    Answer:(20+19.0×1.5+18.2×2.0+17.6×6.0+19.7×1.7-(11.2-0.85)×10)×0.36-2×7.4×0.60+(11.2-0.85)×10=137.9964
