Question: I have to write a program that lets the user enter in as many numbers as he wants and determine which is the largest, smallest, what the sum is, and the average of all the numbers entered. Am I forced to use arrays to do this or is there another way? If I have to use an array, can someone help me out with an example of how I should be approaching this question? Thanks

Answer: 
The newline character `\n` should be included between the double, however HTML does not allow for line feed, but Thomas Hunter suggested an [hack](https://stackoverflow.com/a/8843665/848250) which consists in using a bunch of white spaces, like so:

```
<%= f.text_area :comment, placeholder: "Comment on your track or                  share your favorite lyrics" %>

```

You can also opt to use the `title` attribute instead.
In Ruby, in general `"\n"` is the new line character.

e.g.:

```
  puts "first line\nsecond line"
  => 
  first line
  second line

```

**However, in your case:**

you seem to try to use the newline character in an `.erb` expression `<%= ... %>`

That does not work, because that will only format the newline in the **raw HTML souce**, 
but in the **formatted HTML** you will not see the newline! :-)

**To see the newline in the formatted HTML**, you need to do something like this:

* either put the two strings in separate DIVs or SPANs
* or put a `<br />` in the string instead of the `"\n"` -- `<br \>` is the HTML newline symbol
