sass function quiz-- do I need quotes ( or unquote )

If I'm multiplying the $input in the $function by two ($input *2) does the 2 need quotes? M Sorry if this is confusing.

It doesn't need quotes, and in fact, I think quotes would cause an error. Using quotes would cause the two to change from a number to a string, and you can't multiply a length by a string. 

@function double($input) {
  @return $input * 2 // Works as expected
}

@function double($input) {
  @return $input * "2" // Does not work, since you can't multiply a length by a string.
}

Hopefully this helps answer your question. :)

You don't need to put the double quotes to perform operations:

@function double($input) { @return $input * 2; }
