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
