    Work: Calculate the value of equation 0.2×((3.6-0.7)×(7.2-0.6)-1×2.1)×7 .
    Question type: Mathematical calculation
    Solution:
          0.2×((3.6-0.7)×(7.2-0.6)-1×2.1)×7
        =0.2×(2.9×(7.2-0.6)-1×2.1)×7
        =0.2×(2.9×6.6-1×2.1)×7
        =0.2×17.04×7
        =3.408×7
        =23.856

    Answer:0.2×((3.6-0.7)×(7.2-0.6)-1×2.1)×7=23.856
