[1/1 Formula]
Work: Calculate the value of equation (1.5×(12-1)×10)/2*(18.6-10)-((12-1))/2 .
Question type: Mathematical calculation
Solution:
(1.5×(12-1)×10)/2*(18.6-10)-((12-1))/2
=(1.5×11×10)/2*(18.6-10)-((12-1))/2
=165/2*(18.6-10)-((12-1))/2
=165/2*8.6-((12-1))/2
=165/2*8.6-(11)/2
=165/2*8.6-11/2
=82.5*8.6-11/2
=709.5-11/2
=709.5-5.5
=704
Answer:(1.5×(12-1)×10)/2*(18.6-10)-((12-1))/2=704
