Go through Chapter 14&15 and write up a personal tutorial/instruction set/reference guide of info.
This should be done referring only to Chapter 14&15 and the following.
```
          added to your body tag will call your function FIRST as soon as page loads. 
          Why? do this? So that all the page tags, id's , & classes are set up before any JavaScript runs

                      <body onload=" myBeginFcn()">


          added to any html tag inside the body of the page which is visible on display

                      onclick=


          JavaScript
                      innerHTML
                      Math.random
                      Math.sqrt
                         and any other function inside the Math 'library'

                      document.getElementById(id)
                      document.getElementsByTagName(name) 
                      document.getElementsByClassName(name) 
```
DO NOT ANY WEB TUTORIAL OR DOCUMENTATION.
Your tutorial should generally follow the chronology of the chapter.
For this I want multiple pages of web source:
1. Your list of exercise descriptions with full instructions. These should be simple, clear, and your best attempt at more interesting than those used in the text. As appropriate briefly explain what you are doing and/or why
  WITH LINKS to relevant examples OF YOUR OWN CREATION.
2. DrDale's Example disabled while you work on your own!
  FYI ONLY: Control-Shift-J will display the java console with errors!
3. Do not at any time use document.write() in your code
4. Do not at any time use any 'anonymous' functions If you don't know what I'm talking about.... ask.
AFTER YOU HAVE COMPLETED CHAPTER 14&15 exercise(s) above, a
calculator
of your own devising again based ONLY on material 'allowed' explicitly above.
~~Before you leave~~ By 10pm March 29, send an email to me which includes your source files. Attachments or tar as you prefer but...
