[1/1 Formula]
    Work: Calculate the value of equation (0.7×19.1-0.7×10)×3.12+2×8.3×1.77+0.7×10 .
    Question type: Mathematical calculation
    Solution:
          (0.7×19.1-0.7×10)×3.12+2×8.3×1.77+0.7×10
        =6.37×3.12+2×8.3×1.77+0.7×10
        =19.8744+2×8.3×1.77+0.7×10
        =19.8744+16.6×1.77+0.7×10
        =19.8744+29.382+0.7×10
        =19.8744+29.382+7
        =49.2564+7
        =56.2564

    Answer:(0.7×19.1-0.7×10)×3.12+2×8.3×1.77+0.7×10=56.2564
