I have problems with expressions..
Susan had 24 stamps. She used some to mail letters..
What expression could I write for that?
Also..
Nancy had 23 books. Her dad bought some books and gave Nancy all but 3 of them.

bobpursley,
1) what about
24n where n is the number mailed.
2)
23+(b3) where b is the number of books dad bought.
