[1/1 Formula]
    Work: Calculate the value of equation 1.5*(51-40)*(51-40-1)+12*13+0.5*(40-12)*(40-12-1) .
    Question type: Mathematical calculation
    Solution:
          1.5*(51-40)*(51-40-1)+12*13+0.5*(40-12)*(40-12-1)
        =1.5*11*(51-40-1)+12*13+0.5*(40-12)*(40-12-1)
        =1.5*11*10+12*13+0.5*(40-12)*(40-12-1)
        =1.5*11*10+12*13+0.5*28*(40-12-1)
        =1.5*11*10+12*13+0.5*28*27
        =16.5*10+12*13+0.5*28*27
        =165+12*13+0.5*28*27
        =165+156+0.5*28*27
        =165+156+14*27
        =165+156+378
        =321+378
        =699

    Answer:1.5*(51-40)*(51-40-1)+12*13+0.5*(40-12)*(40-12-1)=699
