Work: Calculate the value of equation ((3.5-0.24)+(4-0.24))×2×2.92-(1.1×1.5+1.5×1.5+0.9×2.1×2)+((3.5-0.24)+(4-0.24))×2×2.92-(1.1×1.5+1.5×2+0.9×2.1) .
Question type: Mathematical calculation
Solution:
((3.5-0.24)+(4-0.24))×2×2.92-(1.1×1.5+1.5×1.5+0.9×2.1×2)+((3.5-0.24)+(4-0.24))×2×2.92-(1.1×1.5+1.5×2+0.9×2.1)
=(3.26+(4-0.24))×2×2.92-(1.1×1.5+1.5×1.5+0.9×2.1×2)+((3.5-0.24)+(4-0.24))×2×2.92-(1.1×1.5+1.5×2+0.9×2.1)
=(3.26+3.76)×2×2.92-(1.1×1.5+1.5×1.5+0.9×2.1×2)+((3.5-0.24)+(4-0.24))×2×2.92-(1.1×1.5+1.5×2+0.9×2.1)
=7.02×2×2.92-(1.1×1.5+1.5×1.5+0.9×2.1×2)+((3.5-0.24)+(4-0.24))×2×2.92-(1.1×1.5+1.5×2+0.9×2.1)
=7.02×2×2.92-7.68+((3.5-0.24)+(4-0.24))×2×2.92-(1.1×1.5+1.5×2+0.9×2.1)
=7.02×2×2.92-7.68+(3.26+(4-0.24))×2×2.92-(1.1×1.5+1.5×2+0.9×2.1)
=7.02×2×2.92-7.68+(3.26+3.76)×2×2.92-(1.1×1.5+1.5×2+0.9×2.1)
=7.02×2×2.92-7.68+7.02×2×2.92-(1.1×1.5+1.5×2+0.9×2.1)
=7.02×2×2.92-7.68+7.02×2×2.92-6.54
=14.04×2.92-7.68+7.02×2×2.92-6.54
=40.9968-7.68+7.02×2×2.92-6.54
=40.9968-7.68+14.04×2.92-6.54
=40.9968-7.68+40.9968-6.54
=33.3168+40.9968-6.54
=74.3136-6.54
=67.7736
Answer:((3.5-0.24)+(4-0.24))×2×2.92-(1.1×1.5+1.5×1.5+0.9×2.1×2)+((3.5-0.24)+(4-0.24))×2×2.92-(1.1×1.5+1.5×2+0.9×2.1)=67.7736
