[1/1 Formula]
Work: Calculate the value of equation 3/2*(52-40)*(51-40)+18*13+1/2*(40-18)*(40-18-1) .
Question type: Mathematical calculation
Solution:
3/2*(52-40)*(51-40)+18*13+1/2*(40-18)*(40-18-1)
=3/2*12*(51-40)+18*13+1/2*(40-18)*(40-18-1)
=3/2*12*11+18*13+1/2*(40-18)*(40-18-1)
=3/2*12*11+18*13+1/2*22*(40-18-1)
=3/2*12*11+18*13+1/2*22*21
=1.5*12*11+18*13+1/2*22*21
=18*11+18*13+1/2*22*21
=198+18*13+1/2*22*21
=198+234+1/2*22*21
=198+234+0.5*22*21
=198+234+11*21
=198+234+231
=432+231
=663
Answer:3/2*(52-40)*(51-40)+18*13+1/2*(40-18)*(40-18-1)=663
