Work: Calculate the value of equation (1550+100-20×2+15×18×2)×2×5+(4700+400+500-20×2+15×20×2)×3×5 .
Question type: Mathematical calculation
Solution:
(1550+100-20×2+15×18×2)×2×5+(4700+400+500-20×2+15×20×2)×3×5
=2150×2×5+(4700+400+500-20×2+15×20×2)×3×5
=2150×2×5+6160×3×5
=4300×5+6160×3×5
=21500+6160×3×5
=21500+18480×5
=21500+92400
=113900
Answer:(1550+100-20×2+15×18×2)×2×5+(4700+400+500-20×2+15×20×2)×3×5=113900
