messages.content: Out of the 10 books, 10 x 2/5 = <<10*2/5=4>>4 are reading books.
  While 10 x 3/10 = <<10*3/10=3>>3 are math books.
  There are 3 - 1 = <<3-1=2>>2 science books.
  So, the total number of reading, math, and science books is 4 + 3 + 2 = <<4+3+2=9>>9.
  Thus, there is only 10 - 9 = <<10-9=1>>1 history book.
