A bookshelf has 5 rows of books. Eachrow has8 books. If 2 books are removed from each row, how many books are left?
There are 5 rows of books, each row having 8 books, so there are a total of 5 * 8 = <<5*8=40>>40 books on the bookshelf.
If 2 books are removed from each row, a total of 2 * 5 = <<2*5=10>>10 books are removed.
Therefore, there are 40 - 10 = <<40-10=30>>30 books left. Answer: \boxed{30}.
If there are 5 rows of books, and each row has 8 books, the total number of books on the bookshelf would be 5 rows * 8 books/row = 40 books.
If 2 books are removed from each row, we need to subtract 2 books from each row. So, the total number of books remaining would be 40 books - (5 rows * 2 books/row) = 40 books - 10 books = 30 books.
Therefore, there are 30 books left on the bookshelf.
