 ## Day 1 Questions
 
 1. How would you print the string `"Hello World!"` to the terminal?
-
+'''ruby
+puts "Hello World!"
+'''
 1. What character is used to indicate comments in a ruby file?
-
+"#"
 1. Explain the difference between an integer and a float?
-
+An integer is a whole number (1, 5, -3) and a float contains a decimal (1.5, 5.3, 0.01)
 1. In the space below, create a variable `animal` that holds the string `"zebra"`
-
+'''ruby
+animal = "zebra"
+'''
 1. How would you print the string `"zebra"` using the variable that you created above?
-
+'''ruby
+puts animal
+'''
 1. What is interpolation? Use interpolation to print a sentence using the variable `animal`.
-
+Interpolation in ruby is including results of code within a string, such as the results of variables and calculations.
+'''ruby
+puts "Can you draw a #{animal}?"
+'''
+(I tried to look up a way to check if the first letter of the string was a consonant or vowel to make an if/else for the article a/an, but needed to move on before solving)
 1. What method is used to get input from a user?
-
+gets.chomp
 1. Name and describe two common string methods:
+  * .length   returns number of characters in a string
+  * .split    breaks a string into parts and puts into an array; can also take an argument

+  animals = ["cat", "dog", "bird", "snake"]
+  animals.each {|x| print x, " | "}
+  ```
+  ```
+  cat | dog | bird | snake
+  ```
+
+.join -- connects string elements into one strong
+
+.include?() -- find if an array contains an element
+
+.first -- returns first element
+.last -- returns last element
+
+.length .count .size -- returns number of elements
+
+.insert(position, element(s)) -- inserts one or more elements at the specified position
+
+.unshift -- add to the beginning of an array
+
+.pop -- removes and returns last element
+
+.uniq -- removes duplicates from array
