/*
 * Create a simple calculator
 * I should be able to do basic add/sub/mult/divd and be able to use "()"
 *
 * 1. Take user input
 *      a. Check to see if there is a previous answer that we are going to act on
 *          1. initialize answer to 0
 *          2. if the user starts with an operand, the first number is "answer"
 *             else, start a new problem with whatever the user puts in
 *      b. Parse user input for ( ) / * - + in order to formulate a proper math problem
 *          1. Strip trailing and leading white space
 *          2. Check to see if there is a library that converts a string to a math problem
 *      c. check for the clear command
 * 2. Calculate the answer
 *      a. Take 
 * 3. return the answer above a new prompt in a clered screen
