 ## Day 3 Questions
 
 1. What is a conditional statement? Give three examples.
+A conditional statement is if this then that. Examples of this are:
+If x is greater than y then x is pink
+If x is less than y then x is green
+If it is cloudy outside there will be meatballs.
 
 1. Why might you want to use an if-statement?
+To give folks an option and a more specified response to their input.
 
-1. What is the Ruby syntax for an if statement?
+1. What is the Ruby syntax for an if statement? after the variables are defined
+if *variable*  **operator** *variable assignment*
+puts "desired statement"
+end
 
 1. How do you add multiple conditions to an if statement?
+ adding "and"
 
 1. Provide an example of the Ruby syntax for an if/elsif/else statement:
+if homework == finished
+puts "alex can relax"
+elsif homework == unfinished
+puts "alex is still in panic town"
+end
 
 1. Other than an if-statement, can you think of any other ways we might want to use a conditional statement?
+When this happens this happens maybe?

 ## Day 4 Questions
 
 1. In your own words, what is the purpose of a method?
-
+ The purpose of a method is to have the code do something multiple times to different things without having to retype what you want it to do each time.
 1. Create a method named `hello` that will print `"Sam I am"`.
+ def hello
+    p "Sam I am"
+ end
 
+  hello     <-- that would call the method
 1. Create a method named `hello_someone` that takes an argument of `name` and prints `"#{name} I am"`.
+ def hello_someone(name)
+  p "#{name} I am"
+ end
 
 1. How would you call or execute the method that you created above?
+  hello_someone ("Sam")
 
 1. What questions do you have about methods in Ruby?
+What is the difference between a parameter and an argument?

 ## Day 5 Questions
 
 1. What is a Hash, and how is it different from an Array?
-
+  A hash is a collection of keys and values that are unordered. An array is an ordered list that has an integer index.
 1. In the space below, create a Hash stored to a variable named `pet_store`.  This hash should hold an inventory of items and the number of that item that you might find at a pet store.
-
+  pet_store = {bird_seed:4, dog_bed:5, cat_tower:6}
+  p pet_store
 1. Given the following `states = {"CO" => "Colorado", "IA" => "Iowa", "OK" => "Oklahoma"}`, how would you access the value `"Iowa"`?
-
+  p states[IA]
 1. With the same hash above, how would we get all the keys?  How about all the values?
-
+  p states.keys  p states.values
 1. What is another example of when we might use a hash?  In your example, why is a hash better than an array?
-
+  If we had a list of dance moves in a dance ie: dance_moves = {'plie'=>'bend the knees','chaine'=>'chain turn','sote'=>'little jump in first position'}
+  p dance_moves
+   A hash is better than an array because it allows the freedom to look for values based on the key ie dance moves in this example rather than where they exist in the list. This would be great for a how to program for this little dance.
 1. What questions do you still have about hashes?
+  I would just like an ELI5 chat about hashes because I *think* I get it but I want to make sure I get it. Mostly because I am not sure if my answer to the preceding question was correct.

-## Day 6 Questions
+The The Day 6 Questions
 
 1. In your own words, what is a Class?
-
+A class is the category of a thing where every one of the things in that category have the same kinds of things. It's the mold that item/object/instance is shaped with.
 1. What is an attribute of a Class?
-
+An attribute of a class is a piece of the mold that every single instance of a class has.
 1. What is behavior of a Class?
-
+A behavior, similar to an attribute, is a piece of the mold that every instance of a class has. While an attribute describes, the behaviors are all things that a class can do or be done to it.
 1. In the space below, create a Dog class with at least 2 attributes and 2 behaviors:
+``class Doggo
+  attr_reader :face_shape, :name
+  def initialize(face_shape, name)
+  @face_shape = face_shape
+  @name       = name
+  end
 
-1. How do you create an instance of a class?
+    def sing
+     p "bark bark bark"
+    end
 
+    def tail_wag
+    p "Look at #{name} wagging their tail!"
+    end
+end
+``
+1. How do you create an instance of a class?
+use the .new method 
 1. What questions do you still have about classes in Ruby?
+I'm actually pretty confused still. I am going to try digging into the practice exercises. Also I couldn't figure out how to get it to stop printing twice.
