Work: Calculate the value of equation ((1.4+1.6)×2×0.5+(2.22+2.8)×2×0.5+(3.04+4)×2×0.5)×2+((1.4+4.3)×2×0.5+(2.22+5.4)×2×0.5+(3.04+6.5)×2×0.5)×1 .
Question type: Mathematical calculation
Solution:
((1.4+1.6)×2×0.5+(2.22+2.8)×2×0.5+(3.04+4)×2×0.5)×2+((1.4+4.3)×2×0.5+(2.22+5.4)×2×0.5+(3.04+6.5)×2×0.5)×1
=(3×2×0.5+(2.22+2.8)×2×0.5+(3.04+4)×2×0.5)×2+((1.4+4.3)×2×0.5+(2.22+5.4)×2×0.5+(3.04+6.5)×2×0.5)×1
=(3×2×0.5+5.02×2×0.5+(3.04+4)×2×0.5)×2+((1.4+4.3)×2×0.5+(2.22+5.4)×2×0.5+(3.04+6.5)×2×0.5)×1
=(3×2×0.5+5.02×2×0.5+7.04×2×0.5)×2+((1.4+4.3)×2×0.5+(2.22+5.4)×2×0.5+(3.04+6.5)×2×0.5)×1
=15.06×2+((1.4+4.3)×2×0.5+(2.22+5.4)×2×0.5+(3.04+6.5)×2×0.5)×1
=15.06×2+(5.7×2×0.5+(2.22+5.4)×2×0.5+(3.04+6.5)×2×0.5)×1
=15.06×2+(5.7×2×0.5+7.62×2×0.5+(3.04+6.5)×2×0.5)×1
=15.06×2+(5.7×2×0.5+7.62×2×0.5+9.54×2×0.5)×1
=15.06×2+22.86×1
=30.12+22.86×1
=30.12+22.86
=52.98
Answer:((1.4+1.6)×2×0.5+(2.22+2.8)×2×0.5+(3.04+4)×2×0.5)×2+((1.4+4.3)×2×0.5+(2.22+5.4)×2×0.5+(3.04+6.5)×2×0.5)×1=52.98
