I have problems with expressions..
Susan had 24 stamps. She used some to mail letters..
What expression could I write for that?
Nancy had 23 books. Her dad bought some books and gave Nancy all but 3 of them.
1) what about
24-n where n is the number mailed.
23+(b-3) where b is the number of books dad bought.
MR SPIDER HAS 7 TIMS AS MANY FLIES AS HE DOES BEETLES. ALTOGETHER HE HAS 48. HOW MANY FLIES AND HOE MANY BEETLES DOES MR SPIDER HAVE?
thank you so much
