Two ways of joining Array elements

You can use Array#join to concatenate Array elements to a String:

[1, 2, 3].join('+')
# => "1+2+3"

Array#* has the same effect when you pass it a String:

[1, 2, 3] * '+'
# => "1+2+3"

You can use HTML tags for formatting. Wrap code in <code> tags and multiple lines of code in <pre><code> tags.
