[Solved] Very Basic Ruby puts and gets

Question

It always helps if you include the error. There are two ways to fix that error:

Interpolate the value: puts "you would like #{number} much better"
Turn it from a number to a string: puts "you would like " + number.to_s + 'much better'

The former, #{...} syntax, evaluates the content of the braces as Ruby, and then applies to_s to the result, before injecting it into the string. My two examples are literally equivalent.

As to why it fails? + doesn’t do type coercion in Ruby, which actually has very little implicit conversion going on, unlike other languages in similar spaces.
