how did you know it was multiplicaton instead of division or addition

math  Ms. Sue, Friday, August 27, 2010 at 7:59pm
You could add.
First friend = 3 cookies
Second friend = 3 cookies
Third friend = 3 cookies
Fourth friend = 3 cookies
and so on
But it's certainly quicker to multiply the number of friends by the number of cookies each should get.
