+Now lets explore what a variable is.

-So the key is we need to add the name:

 Mark: 100%
-Comment: Roger got the right answer, but I had to tell him to fix the English formatting, including to add a space between a + c. After he changed it to a + " " + c the program was acceptable for APSC. I'll give him the 100% for now, but otherwise a program with a missing space is at best 90% or 93%.
+Comment: Many students don't format the English correctly, or forget to include a space between the two words. In such a case they should lose 5% for the mistake.
