+# Ruby Practice
+
+Run your Ruby file by typing `ruby ` and then the name of the file you want to run in the Terminal.
+
+If we want to run `hash_person.rb`, we can write the command:
+
+```bash
+ruby hash_person.rb
+```
+
+To re-run this command, you can use the UP and DOWN arrow keys to look at the history of commands you've run in a Terminal.
+
+## Hash
+
+### hash_person.rb
+Input:
+```
+Maude 24 Artist
+```
+
+Key output:
+`{ :name => "Maude", :age => 24, :occupation => "Artist" }`
+
+Complete input and output example:
+```bash
+"Enter a name, age, and occupation separated by spaces:"
+Maude 24 Artist
+{ :name => "Maude", :age => 24, :occupation => "Artist" }
+```
+
+###### Make sure the value of the :age key is an Integer
+
+### hash_dig.rb
+
+Write a program that uses the `sample_hash` variable and prints the value of key "history"
+
+```ruby
+sample_hash = {
+   :class => { 
+      :student => { 
+         :name => "Mike",
+         "marks" => { 
+            "physics" => 70,
+            "history" => 80
+         }
+      }
+   }
+}
+```
+
+### hash_find_value.rb
+
+Write a program that:
+   Asks the user for an Integer, then checks to see if that integer is
+   a value of any of the keys in sample_hash.
+   If you find the number, print out "100 is under the key: a."
+   If you don't find the number print out "Could not find the integer 100"
+
+Example:
+
+```bash
+"Enter an integer:"
+4
+"Could not find the integer 4"
+```
+
+### hash_list.rb
+
+Given this list of people, print only names of people who are at least 16.
+
+Yes, you could just look at it with your eyes and print their names, but imagine that you couldn't because there are a million items in the list.
+
+Use the variable, loops, and conditionals instead.
+
+Output something like:
+
+```bash
+"Jerry"
+"Sloane"
+"Hurly"
+```
+
+## Specs
+<details>
+  <summary>Click here to see names of each test</summary>
+
+hash_person.rb prints Hash of '{:name => "Osi", :age => 24, :occupation => "Songwriter"}', when input is 'Osi 24 Songwriter' 
+
+hash_person.rb prints Hash of '{:name => "Lia", :age => 32, :occupation => "Engineer"}', when input is 'Lia 32 Engineer' 
+
+hash_find_value.rb prints Hash of 'Could not find the integer 4', when input is '4' 
+
+hash_find_value.rb prints Hash of '100 is under the key: a.', when input is '100' 
+
+hash_find_value.rb prints Hash of '22 is under the key: e.', when input is '22' 
+
+hash_find_value.rb prints Hash of '32 is under the key: e.', when input is '32' 
+
+hash_dig.rb prints '80' by retriving the value from the Hash 
+
+hash_list.rb prints 'James', 'Yolanda', 'Red', and  'Fatimah' using variables, loops, if statements, and Hash methods'
