Programming Basics:

    Data -       information
    Statements - how we wish to mainpulate the data

    Algorithm -  Sequence of instructions to solve a task

    Stepwise Refinement
       - take the steps from an algorithm and break them
            into smaller steps, until each step is a 
            single line of a computer's instruction

    Statements can differ based on the programming language 
         being used

    Program - a collection of statements in a given programming
         language


    Data gets stored in the Computer's RAM Memory
      The instructions are able to access different locations
         into the RAM Memory
      Between the execution of two instructions the data
         are stored in the RAM memory

    In a program, we use names to refer to the RAM Memory locations
      "variables" is the term used to refer to these names

    We might use the variables name of:
       exam1, exam2, exam3, average 
    in a program calculating the average test score.

    # one possible example of a python program to do the above

    exam1 =   96
    exam2 =  100
    exam3 =   35

    average = ( exam1 + exam2 + exam3 ) / 3

    print average


Assignment Statement:

    Syntax:

      <varName>   =   <expression>

Mathimatical Operators

1.   (  )
2.   *  /
3.   +  -

Assignment Statements are NOT algebraic statements

      index = index + 1

   Step 1.  Evaluate the RIGHT HAND SIDE of the equal sign
   Step 2.  Store the value into the variable on the LEFT HAND SIDE
