After a late night of math studying, you and your friends decide to go to your favorite tax$-$free fast food Mexican restaurant, Burrito Chime. You decide to order off of the dollar menu, which has $6$ items. Your group has $$13$ to spend $($and will spend all of it$).$

How many different orders are possible? $($The order in which the order is placed does not matter $-$ just which and how many of each item that is ordered.$)$

How many different orders are possible if you want to get at least one of each item?

How many different orders are possible if you don$$t get more than $4$ of any one item?
