Work: Calculate the value of equation 23.86×(1.67-1)-1/2×(1.67-0.98)×(13.1×1.67-12.85)×2×1/3×(1.67-0.98) .
Question type: Mathematical calculation
Solution:
23.86×(1.67-1)-1/2×(1.67-0.98)×(13.1×1.67-12.85)×2×1/3×(1.67-0.98)
=23.86×0.67-1/2×(1.67-0.98)×(13.1×1.67-12.85)×2×1/3×(1.67-0.98)
=23.86×0.67-1/2×0.69×(13.1×1.67-12.85)×2×1/3×(1.67-0.98)
=23.86×0.67-1/2×0.69×9.027×2×1/3×(1.67-0.98)
=23.86×0.67-1/2×0.69×9.027×2×1/3×0.69
=15.9862-1/2×0.69×9.027×2×1/3×0.69
=15.9862-0.5×0.69×9.027×2×1/3×0.69
=15.9862-0.345×9.027×2×1/3×0.69
=15.9862-3.114315×2×1/3×0.69
=15.9862-6.22863×1/3×0.69
=15.9862-6.22863/3×0.69
=15.9862-2.07621×0.69
=15.9862-1.432585
=14.553615
Answer:23.86×(1.67-1)-1/2×(1.67-0.98)×(13.1×1.67-12.85)×2×1/3×(1.67-0.98)=14.553615
