A bookshelf has 5 rows of books. Eachrow has8 books. If 2 books are removed from each row, how many books are left?

Answer 1

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}.
