 Functions can take variables arguments as input, and may return variables as output.
 
-Here's a few handy functions, with some examples:
-
-input(prompt): Prompts the user for input by showing the prompt screen, returning whatever the user entered after they hit <enter>.
+Here's a few handy functions built in to Python:
+
+ * `input(prompt)`: Prompts the user for input by showing the prompt screen, returning whatever the user entered after they hit <enter>.
+ * `pow(x,y)`:  Return x^y^
+ * `round(x,[n])`:  Rounds a decimal number x to n digits after the decimal point.  The [] means that the n is optional, if you don't include it, n=0.
+ * `sum(iterable)`:  Sums all the numbers in the list ''iterable''.
+
+
+
+Here's some examples of how they're used (don't forget to look at earlier lessons for range() and print().
+
+{{
+
+a=input("Pick a number, any number)
+
+print(a);
+
+b = pow(2,2)
+
+print(b) [ticket:4 # Answer is 4]
+
+c = round(3.14159, 2)
+
+print(c) #Answer is 3.14
+
+d = sum([1,2,3,4])
+
+print(d) # Answer is 10

+}}}
