There are two errors in the script.  You need to help Ruby know when  
to convert the objects you are working with...

> puts 'What is your favorite number?'
> num = gets.chomp
> num=num +1

num = num.to_i + 1 # we have a String, but want an Integer

> puts 'Well this ' + num + ' might be better.'

# now we need to go back to a String so we can concatenate
puts 'Well this ' + num.to_s + ' might be better.'

Does that help?
