how did you know it was multiplicaton instead of division or addition
Answered by Ms. Sue
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.
