Work: Calculate the value of equation (1-0.1)×5.8×16.1-(0.4+0.8)/2×0.4×16.1-0.3×0.4×16.1 .
Question type: Mathematical calculation
Solution:
(1-0.1)×5.8×16.1-(0.4+0.8)/2×0.4×16.1-0.3×0.4×16.1
=0.9×5.8×16.1-(0.4+0.8)/2×0.4×16.1-0.3×0.4×16.1
=0.9×5.8×16.1-1.2/2×0.4×16.1-0.3×0.4×16.1
=5.22×16.1-1.2/2×0.4×16.1-0.3×0.4×16.1
=84.042-1.2/2×0.4×16.1-0.3×0.4×16.1
=84.042-0.6×0.4×16.1-0.3×0.4×16.1
=84.042-0.24×16.1-0.3×0.4×16.1
=84.042-3.864-0.3×0.4×16.1
=84.042-3.864-0.12×16.1
=84.042-3.864-1.932
=80.178-1.932
=78.246
Answer:(1-0.1)×5.8×16.1-(0.4+0.8)/2×0.4×16.1-0.3×0.4×16.1=78.246
