[1/1 Formula]
Work: Calculate the value of equation (0.65+1.75)*0.65/2-(0.4+1.75)*0.4/2 .
Question type: Mathematical calculation
Solution:
(0.65+1.75)*0.65/2-(0.4+1.75)*0.4/2
=2.4*0.65/2-(0.4+1.75)*0.4/2
=2.4*0.65/2-2.15*0.4/2
=1.56/2-2.15*0.4/2
=0.78-2.15*0.4/2
=0.78-0.86/2
=0.78-0.43
=0.35
Answer:(0.65+1.75)*0.65/2-(0.4+1.75)*0.4/2=0.35
