Work: Calculate the value of equation 2.8*5.5+(0.2*1.1+3.6*1.8)*2+(0.15*2.25+1.6*0.6)*2+2.8*3+(3.6*0.3+2.2*1.6)+3.02*1.2+1.2+0.6*1.6+0.6*1.8 .
Question type: Mathematical calculation
Solution:
2.8*5.5+(0.2*1.1+3.6*1.8)*2+(0.15*2.25+1.6*0.6)*2+2.8*3+(3.6*0.3+2.2*1.6)+3.02*1.2+1.2+0.6*1.6+0.6*1.8
=2.8*5.5+6.7*2+(0.15*2.25+1.6*0.6)*2+2.8*3+(3.6*0.3+2.2*1.6)+3.02*1.2+1.2+0.6*1.6+0.6*1.8
=2.8*5.5+6.7*2+1.2975*2+2.8*3+(3.6*0.3+2.2*1.6)+3.02*1.2+1.2+0.6*1.6+0.6*1.8
=2.8*5.5+6.7*2+1.2975*2+2.8*3+4.6+3.02*1.2+1.2+0.6*1.6+0.6*1.8
=15.4+6.7*2+1.2975*2+2.8*3+4.6+3.02*1.2+1.2+0.6*1.6+0.6*1.8
=15.4+13.4+1.2975*2+2.8*3+4.6+3.02*1.2+1.2+0.6*1.6+0.6*1.8
=15.4+13.4+2.595+2.8*3+4.6+3.02*1.2+1.2+0.6*1.6+0.6*1.8
=15.4+13.4+2.595+8.4+4.6+3.02*1.2+1.2+0.6*1.6+0.6*1.8
=15.4+13.4+2.595+8.4+4.6+3.624+1.2+0.6*1.6+0.6*1.8
=15.4+13.4+2.595+8.4+4.6+3.624+1.2+0.96+0.6*1.8
=15.4+13.4+2.595+8.4+4.6+3.624+1.2+0.96+1.08
=28.8+2.595+8.4+4.6+3.624+1.2+0.96+1.08
=31.395+8.4+4.6+3.624+1.2+0.96+1.08
=39.795+4.6+3.624+1.2+0.96+1.08
=44.395+3.624+1.2+0.96+1.08
=48.019+1.2+0.96+1.08
=49.219+0.96+1.08
=50.179+1.08
=51.259
Answer:2.8*5.5+(0.2*1.1+3.6*1.8)*2+(0.15*2.25+1.6*0.6)*2+2.8*3+(3.6*0.3+2.2*1.6)+3.02*1.2+1.2+0.6*1.6+0.6*1.8=51.259
