 Tuples are useful in specific cases. Namely, when an explicit number of elements and their types are known. Tuples are designated by parentheses '()'
 
+Also interestingly, tuples can have a mish mash of types inside them. The specific combination of types inside a tuple makes the tuple itself a certain type:
+
+```haskell
+[(1,2), (3,4), (5,6)] -- is okay!
+[(1,2), (8,5,11), (5,6)] -- is NOT okay!
+[(1,2), ('Okay?', 2)] -- is NOT okay!
+```
+
+Tuples have special names for their sizes:
+(1,2) - Pair
+(3,4,5) - Triple
+(4,5,6,7) - 4-tuple
+(2,3,..,n) - n-tuple
+
+Here's some useful tuple functions:
+fst: takes a pair and returns first component
+snd: Suprise! gives the second component of a pair
+zip: Takes two lists and makes pairs of the elements. Stops at the shorter list's end.
