Subject: convert s to i, then + 1

Hi all, I am very to new to ruby and am having trouble writing a very
simple program: basically i just want to ask for an integer then return
the integer +1
here is my code:
---------------------------------------------------
puts 'what\'s your favorite number?'
var1 = 1
num = gets.chomp
puts 'well ' + num.to_i + ' + var1 is better'

------------------------

when I run it, this is the error i get:
---------------------------------------
what's your favorite number?
3
ri20min.rb:5:in `+': can't convert Fixnum into String (TypeError)
  from ri20min.rb:5:in `<main>'
---------------------------------------
I realize this is laughable, but I am struggling with the concept, any
help is greatly appreciated.
