[1/1 Formula]
    Work: Calculate the value of equation (20+19.4×1.79+19.2×2.9+19.8×1.79)×0.61-2×31×0.87 .
    Question type: Mathematical calculation
    Solution:
          (20+19.4×1.79+19.2×2.9+19.8×1.79)×0.61-2×31×0.87
        =145.848×0.61-2×31×0.87
        =88.96728-2×31×0.87
        =88.96728-62×0.87
        =88.96728-53.94
        =35.02728

    Answer:(20+19.4×1.79+19.2×2.9+19.8×1.79)×0.61-2×31×0.87=35.02728
