Question

Suzanne has 13 bookmarks in

her collection. She started with
4 bookmarks. How many more
bookmarks did she buy after
she started her collection?

She bought 9 more bookmarks after she started her collection. Because when you subtract the total amount of bookmarks she has now to the total amount of bookmarks she had when she started, you will get 9! So that's how much bookmarks were bought after Suzanne started the collection.

13 - 4 = 9
