Work: Calculate the value of equation (20.7-0.48×2-0.6×2)×((4.2-0.7)×2+(4.2-0.35))-4.05-7.2 .
Question type: Mathematical calculation
Solution:
(20.7-0.48×2-0.6×2)×((4.2-0.7)×2+(4.2-0.35))-4.05-7.2
=18.54×((4.2-0.7)×2+(4.2-0.35))-4.05-7.2
=18.54×(3.5×2+(4.2-0.35))-4.05-7.2
=18.54×(3.5×2+3.85)-4.05-7.2
=18.54×10.85-4.05-7.2
=201.159-4.05-7.2
=197.109-7.2
=189.909
Answer:(20.7-0.48×2-0.6×2)×((4.2-0.7)×2+(4.2-0.35))-4.05-7.2=189.909
