Having a little bit of difficulty following, I assume you meant "if the user
*enters* *4*, then tell them they did it correctly".

In which case you could have it like this:

print "2 + 2 = "
input = gets.chomp # chomp removes the newline from pressing the enter key
if input == '4' # remember input comes in as a String, so we compare to
String representation of 4
  puts 'correct'
else
  puts 'wrong'
end
