[1/1 Formula]
    Work: Calculate the value of equation ((3.5-0.24)+(4-0.24))×2×2.92-(1.1×1.5+1.5×1.5+0.9×2.1×2)+((3.5-0.24)+(4-0.24))×2×2.92-(1.1×1.5+1.5×2+0.9×2.1) .
    Question type: Mathematical calculation
    Solution:
          ((3.5-0.24)+(4-0.24))×2×2.92-(1.1×1.5+1.5×1.5+0.9×2.1×2)+((3.5-0.24)+(4-0.24))×2×2.92-(1.1×1.5+1.5×2+0.9×2.1)
        =(3.26+(4-0.24))×2×2.92-(1.1×1.5+1.5×1.5+0.9×2.1×2)+((3.5-0.24)+(4-0.24))×2×2.92-(1.1×1.5+1.5×2+0.9×2.1)
        =(3.26+3.76)×2×2.92-(1.1×1.5+1.5×1.5+0.9×2.1×2)+((3.5-0.24)+(4-0.24))×2×2.92-(1.1×1.5+1.5×2+0.9×2.1)
        =7.02×2×2.92-(1.1×1.5+1.5×1.5+0.9×2.1×2)+((3.5-0.24)+(4-0.24))×2×2.92-(1.1×1.5+1.5×2+0.9×2.1)
        =7.02×2×2.92-7.68+((3.5-0.24)+(4-0.24))×2×2.92-(1.1×1.5+1.5×2+0.9×2.1)
        =7.02×2×2.92-7.68+(3.26+(4-0.24))×2×2.92-(1.1×1.5+1.5×2+0.9×2.1)
        =7.02×2×2.92-7.68+(3.26+3.76)×2×2.92-(1.1×1.5+1.5×2+0.9×2.1)
        =7.02×2×2.92-7.68+7.02×2×2.92-(1.1×1.5+1.5×2+0.9×2.1)
        =7.02×2×2.92-7.68+7.02×2×2.92-6.54
        =14.04×2.92-7.68+7.02×2×2.92-6.54
        =40.9968-7.68+7.02×2×2.92-6.54
        =40.9968-7.68+14.04×2.92-6.54
        =40.9968-7.68+40.9968-6.54
        =33.3168+40.9968-6.54
        =74.3136-6.54
        =67.7736

    Answer:((3.5-0.24)+(4-0.24))×2×2.92-(1.1×1.5+1.5×1.5+0.9×2.1×2)+((3.5-0.24)+(4-0.24))×2×2.92-(1.1×1.5+1.5×2+0.9×2.1)=67.7736
