Work: Calculate the value of equation ((0.2+0.3*2)*(2.8+2.45)+0.2*0.5-0.2*0.5*3-0.12*2.5*2)*3 .
Question type: Mathematical calculation
Solution:
((0.2+0.3*2)*(2.8+2.45)+0.2*0.5-0.2*0.5*3-0.12*2.5*2)*3
=(0.8*(2.8+2.45)+0.2*0.5-0.2*0.5*3-0.12*2.5*2)*3
=(0.8*5.25+0.2*0.5-0.2*0.5*3-0.12*2.5*2)*3
=3.4*3
=10.2
Answer:((0.2+0.3*2)*(2.8+2.45)+0.2*0.5-0.2*0.5*3-0.12*2.5*2)*3=10.2
