Good job, Jeff. :sparkles: 

My overall comments are:

* Spaces between math operators is important for readability :space_invader: 
* Nice use of `print` and `Time` :smile:

#### Exercise 6

Your program crashes with a runtime error if I supply 0 as my favorite number.

```
$ ruby 6_bigger_better_favorite_number.rb
What's your favorite number? 0
0... meh, I mean I GUESS that number is okay
6_bigger_better_favorite_number.rb:13:in `/': divided by 0 (ZeroDivisionError)
	from 6_bigger_better_favorite_number.rb:13:in `<main>'
```

Luckily for you, division is not a requirement for this problem.

#### Exercise 8

Your solution demonstrates that you understand the problem. :+1:  

But you failed to incorporate the correct line width from the sample output. Since this is a pixel pushing problem, I have to subtract 1 point.
