 * Requirements
 
-   - Create a program to add and remove integer values from a list
+   - Create a program to build a list of simple mathematical equations and then
+     print out if, for each equation in the list, the result would be in range
 
-   - Program should allow user to do the following as many times as desired
-
-      - Add an integer in a pre-defined range to the list
-      - Remove all occurrences of an integer from the list
-      - Print the values in the list
+      - Equations are two floating point numbers and a simple operation (+, -, *, /)
 
 * Hints
 
-   - Create (at least) three packages
+   - You should create the following packages
 
-      1. minimum/maximum integer values and maximum number of items in list
-      2. User input (ensure value is in range)
-      3. List Abstract Data Machine
+      - Types package that creates a numeric range, an equation record type, and
+        a mechanism to convert the record to a string
+      - Validation package to verify that the equation result would be in range
+      - List package to store the list of equations, and a mechanism to retrieve
+        each item in the list
 
    - Remember: :code:`with package_name;` gives access to :code:`package_name`
