AshliForbes: Added the general math formatting section

The OER Mechanics WeBWorK project is recording helpful notes during problem development.

=== '''Error Messages:''' ===
'''''"The macro alias was unable to form a URL for the auxiliary file... used in this problem"''''' -DK

Double-check the format of the file uploaded or the image that the code is trying to fetch.

If your computer saved the image as a capitalized .PNG rather than a .png, it will be uploaded to Webwork as .PNG.

When the code subsequently tries to fetch a .png file, it will fail to recognize .PNG as the same file even if they have the same name.

Fix this by renaming the image from .PNG to .png on Webwork in the File Manager. It will not work by changing the code to fetch .PNG instead of .png and leaving the image as .PNG on Webwork.

'''''"Errors parsing PGML: Warning: unknown block type 'balance' in PGML::Format::html::format"''''' -DK

Sorry pal, it looks like you used a single quotation mark ' instead of the grave accent ` somewhere in your code, most likely when you are trying to call for MathJax or Latex formatting.

Check all your square brackets and insert grave accents where needed.

'''''Constant Webwork Error Page when Re-Uploading''''' -DK

Try deleting the file and re-uploading, or simply turn on "Overwrite existing files silently". Be careful when overwriting however; make sure the file is in the right place and that only what you want is changed.

=== Question Templates: ===
Here you will find relevant and easy to use question templates in PDF form with commented code for a variety of general uses.

=== General Math Formatting: ===

====== '''Contexts:''' ======
In PGML, when doing calculations there are different 'contexts' that should be used.

====== '''Variables:''' ======
''Ex.'' $A = random(2, 5, 1);

'A' is the label of the variable, when addressing it throughout the code, it has a to have a '$' in front of it in order to compute. The function random generates a number as 'random(low, high, step)'. In this case, the lowest number is 2, with the highest number being 5 with a step size of 1. This means the numbers could be 2,3,4 or 5. To set any variable '$' '''''must be used''''' or else the file will not compile

===== '''Math Rules:''' =====
''Ex.'' $answer = cos($A*pi)/2;

Computations follow similar rules to Perl. * is multiplication, / is division, + is addition, - is subtraction. Calling pi within computations and functions can be used as shown above. All computations are in '''''radians''''', to use degrees within the written question, simply convert to radians before any computations.

=== '''Uploading Archives (Multiple Problems) ''-''''' BK ===
Webwork can only unpack .tgz or .tar.gz files. Instructions below work for the free archiving program 7zip.

1. Select all your files that you want to upload

2. Right click, select 7zip > Add to archive…

3. Pick "tar" from the Archive Format dropdown

4. Select the .tar file it creates, right click it and add it to archive again

5. This time, select gzip from the dropdown

6. Upload the .tar.gz file to webwork, and it'll automatically unpack it
