A book has 43 chapters. The first chapter is 40 pages long the second chapter is 27 pages long and the third chapter is 28 pages long. How many more pages does the first chapter have than the second chapter?
The first chapter has 40 pages. 
The second chapter has 27 pages. 
The third chapter has 28 pages. 

To find out how many more pages the first chapter has than the second chapter, we need to subtract the number of pages in the second chapter from the number of pages in the first chapter. In other words, we need to find 40 - 27. 

40 - 27 = 13 

Therefore, the first chapter has 13 more pages than the second chapter.
