Just finished giving one copy, more copies than just given =2+2=4.

At present, the number of comic books in the Ming Dynasty is just five times, that is to say, there are four times more comic books in the Ming Dynasty, and there are exactly four comic books. So the number of cartoons just now is: 4÷4= 1.

Current number of books = 1x5=5 books.

Originally there were 5- 1=4 copies.

There were only 1+ 1=2 copies at first.
