Work: Calculate the value of equation (0.6+0.6)×2×3.4×3+(0.6+0.6)×2×4.5×4-0.3×0.6×9-0.25×0.5×7 .
Question type: Mathematical calculation
Solution:
(0.6+0.6)×2×3.4×3+(0.6+0.6)×2×4.5×4-0.3×0.6×9-0.25×0.5×7
=1.2×2×3.4×3+(0.6+0.6)×2×4.5×4-0.3×0.6×9-0.25×0.5×7
=1.2×2×3.4×3+1.2×2×4.5×4-0.3×0.6×9-0.25×0.5×7
=2.4×3.4×3+1.2×2×4.5×4-0.3×0.6×9-0.25×0.5×7
=8.16×3+1.2×2×4.5×4-0.3×0.6×9-0.25×0.5×7
=24.48+1.2×2×4.5×4-0.3×0.6×9-0.25×0.5×7
=24.48+2.4×4.5×4-0.3×0.6×9-0.25×0.5×7
=24.48+10.8×4-0.3×0.6×9-0.25×0.5×7
=24.48+43.2-0.3×0.6×9-0.25×0.5×7
=24.48+43.2-0.18×9-0.25×0.5×7
=24.48+43.2-1.62-0.25×0.5×7
=24.48+43.2-1.62-0.125×7
=24.48+43.2-1.62-0.875
=67.68-1.62-0.875
=66.06-0.875
=65.185
Answer:(0.6+0.6)×2×3.4×3+(0.6+0.6)×2×4.5×4-0.3×0.6×9-0.25×0.5×7=65.185
