[1/1 Formula]
    Work: Calculate the value of equation 3.9×15+3.6+3.3×6+2.2×18+(3.9×17+3.6+3.3×4+2.2×18)×8+3.6+3.3×3 .
    Question type: Mathematical calculation
    Solution:
          3.9×15+3.6+3.3×6+2.2×18+(3.9×17+3.6+3.3×4+2.2×18)×8+3.6+3.3×3
        =3.9×15+3.6+3.3×6+2.2×18+122.7×8+3.6+3.3×3
        =58.5+3.6+3.3×6+2.2×18+122.7×8+3.6+3.3×3
        =58.5+3.6+19.8+2.2×18+122.7×8+3.6+3.3×3
        =58.5+3.6+19.8+39.6+122.7×8+3.6+3.3×3
        =58.5+3.6+19.8+39.6+981.6+3.6+3.3×3
        =58.5+3.6+19.8+39.6+981.6+3.6+9.9
        =62.1+19.8+39.6+981.6+3.6+9.9
        =81.9+39.6+981.6+3.6+9.9
        =121.5+981.6+3.6+9.9
        =1103.1+3.6+9.9
        =1106.7+9.9
        =1116.6

    Answer:3.9×15+3.6+3.3×6+2.2×18+(3.9×17+3.6+3.3×4+2.2×18)×8+3.6+3.3×3=1116.6
