Work: Calculate the value of equation 49.211×(5.75-2.1+0.84)+105.784×(5.75-2.1-3+1.22)+52.94×0.32-207.57×(5.75-2) .
Question type: Mathematical calculation
Solution:
49.211×(5.75-2.1+0.84)+105.784×(5.75-2.1-3+1.22)+52.94×0.32-207.57×(5.75-2)
=49.211×4.49+105.784×(5.75-2.1-3+1.22)+52.94×0.32-207.57×(5.75-2)
=49.211×4.49+105.784×1.87+52.94×0.32-207.57×(5.75-2)
=49.211×4.49+105.784×1.87+52.94×0.32-207.57×3.75
=220.95739+105.784×1.87+52.94×0.32-207.57×3.75
=220.95739+197.81608+52.94×0.32-207.57×3.75
=220.95739+197.81608+16.9408-207.57×3.75
=220.95739+197.81608+16.9408-778.3875
=418.77347+16.9408-778.3875
=435.71427-778.3875
=-342.67323
Answer:49.211×(5.75-2.1+0.84)+105.784×(5.75-2.1-3+1.22)+52.94×0.32-207.57×(5.75-2)=-342.67323
