+Ruby is a programming language from Japan which is revolutionizing
+software development.
+
+The beauty of Ruby is found in its balance between simplicity and power.
+
+You can type some Ruby code in the editor and use these buttons to navigate:
+
+- __Run__ → Executes the code in the editor
+- __Copy__ → Copies the example code to the editor
+- __Next__ → Allows you to go to the next lesson
+- __Back__ → Allows you to return to the previous lesson

+ok:     Only strings can be reversed
+error:  
+---
+
+You can't reverse the number forty. I guess you can hold your monitor up to the mirror, but reversing a number just doesn't make sense.
+
+Ruby has tossed an error message. Ruby is telling you there is no method reverse for numbers.
+
+Maybe if you turn the number into a string first:
+
+    40.to_s.reverse

+And numbers are different from strings.
+
+While you can use methods on any object in Ruby, some methods only work on certain types of things.
+But you can always convert between different types using Ruby's "to" methods.
+
+- __to_s__ converts things to __s__trings
+- __to_i__ converts things to __i__ntegers (numbers)
+- __to_a__ converts things to __a__rrays
+
+__What are arrays?!__
+
+They are lists. Type in a pair of brackets:
+
+    []

+
+Try adding a number to this list: type a comma after 35 followed by a number. The space is optional.

+
+You've hung on to your lotto numbers, tucking them away inside a __variable__ called ticket.
+But any other name, like _jimmyslist_, would have been fine too.
+
+Programming, you will discover, is mostly about working with variables.
+
+Let's put your lotto numbers in order, how about?
+
+Use: 
+
+    ticket.sort!
+    
+You had a list. You sorted the list. The ticket variable is now changed.  
+Did you notice that the _sort!_ method has a big, bright exclamation at the end?  
+A lot of times Ruby methods shout like that if they alter the variable for good.
+It's nothin special, just a mark.

+load:   ticket = [12, 47, 35]
+ok:     Ok
+error:  Almost
+---
+
+So we stored our lotto numbers inside variable ticket. How to get 'em out again?
+
+We already saw that we can get the highest number with __max__. Similarly you can
+get the __first__ or the __last__ element of the list.
+But what if you want a specific element?
+
+### [ ]
+Ruby uses the square brackets [ ] to target an element.
+The square brackets are very common in Ruby.
+They are like sights used to line up a target. Exactly.
+These brackets mean, "I am looking for ____" Ready, aim.
+
+Let's get all of our lotto numbers:
+
+    puts ticket[0]
+    puts ticket[1]
+    puts ticket[2]
+
+Why do we use [0], [1], [2]?
+
+And not [1], [2] and [3]? Is that some kind of Japanese Zen thing?
+No, we computer people just like to begin counting from zero. It's not just a Ruby thing,
+this _zero based indexing_ is used in most programming languages.
+
+> A little reminder: you can use the __Copy__ button to copy the example code to the editor.
