p '...well that\'s an OK number but don\'t you think ' + fav2 + ' is a
little bit bigger and better?'

'...well that\'s an OK number but don\'t you think '
# this is a string (instance of String)

fav2
# this is a Fixnum (could also be Bignum is very big number)

' is a little bit bigger and better?'
# this is a string again

Now, the '+' operator cannot handle adding strings and numbers.

Either:

puts 1 + 3 + 4  #=> 8

puts "I am" + " studying" + " ruby"

Now, you can convert numbers to strings with to_s

and you can convert strings to number with to_i  (or to_f for floats).

So, this will work too:

puts "This is a nicer number:" + 36.to_s

puts 3 + "4".to_i + 5

I leave the exercise to you for your specific code.

HTH,

Peter
