Morgan came home from her vacation at Grandma's with 6 books. While she was away she purchased 3 books at the book store and got 1 book as a gift. During her stay at Grandma's, she also gave her cousin the 2 books that she finished.

How many books did she take with her when she left for her trip?

Morgan started with 4 books.

This is one way to work backwards:

Morgan returned with 6 books.

She gave away 2 of the books that she had.
So add those two books back to her total.
6 + 2 = 8

So subtract that book from her total.
8 - 1 = 7

She bought 3 books that she had not brought with her.
So subtract those books from her total.
7 - 3 = 4

She must have left for vacation with 4 books.
