Work: Calculate the value of equation 49.211×(9-2.1+0.84)+105.784×(9-2.1-3+1.22)+241.001×(9-2.74)-415.80×0.5 .
Question type: Mathematical calculation
Solution:
49.211×(9-2.1+0.84)+105.784×(9-2.1-3+1.22)+241.001×(9-2.74)-415.80×0.5
=49.211×7.74+105.784×(9-2.1-3+1.22)+241.001×(9-2.74)-415.80×0.5
=49.211×7.74+105.784×5.12+241.001×(9-2.74)-415.80×0.5
=49.211×7.74+105.784×5.12+241.001×6.26-415.80×0.5
=380.89314+105.784×5.12+241.001×6.26-415.8×0.5
=380.89314+541.61408+241.001×6.26-415.8×0.5
=380.89314+541.61408+1508.66626-415.8×0.5
=380.89314+541.61408+1508.66626-207.9
=922.50722+1508.66626-207.9
=2431.17348-207.9
=2223.27348
Answer:49.211×(9-2.1+0.84)+105.784×(9-2.1-3+1.22)+241.001×(9-2.74)-415.80×0.5=2223.27348
