Find the number of ways that Magnus can give out $12$ identical stickers to $2$ of his friends. (Not everyone has to get a sticker.)

We can essentially list everything out. 

We have

\(12-0\\ 11-1\\ 10-2\\ 9-3\\ 8-4\\ 7-5\\ 6-6\\ 5-7\\ 4-8\\ 3-9\\ 2-10\\ 1-11\\ 0-12\\\)

As you can see, there are 13 ways we can do this. 

 

Thanks! :)
