Probably the most idiomatic way is to use string interpolation.

Within a double quoted string you can put a Ruby expression in #{ }
delimiters.  The expression will be evaluated and to_s will be sent to
the result replacing the delimited expression so:

Instead of

>> puts 2+4 ' is the sum of 2+4.'

I would probably use:
    puts "#{2+4} is the sum of 2+4"

and for

> puts number + '?? Don\t you know that ' + better + 'is a superior selection?'

puts "#{number}'?? Don\t you know that #{better} is a superior selection?"
