I think there may be a few omissions in the playground solution for the video 2 challenge (viewed in raw): Line 11 should be “myAge,” not “age.” The solution for the problem that begins "Declare a variable of type Double called averageAge. " is missing. Lines 20 and 21 should be Doubles. Bob ---

MISSING - The challenge asks for: “Declare a variable of type Double called averageAge. Initially, set it to your own age. Then, set it to the average of your age and my own age of 30.” But the answer is not in the playground solution. ---

The download for the materials are a mess as of 10 Jul 2017. The missing solution about adding and averaging age is not there despite what the developer says, and there is a secondary zip file containing the same OLD files in the download. Can someone actually look over this with some care and attention please! ---
