A Mathematician's Lament

The 2002 typewritten version is the original version. I might have read all of this sometime years before 2016; I read about 7 pages of this in 2021-10 and found it to be interesting. Due to the PDF being a reupload, I added some bonus mathematics to this item. File "School Math 2015 ... AMS-LaTeX.txt" and file "School Math 2015 ... AMS-LaTeX__Logarithm.png" are probably related to or somewhat related to a 2015 Math class that occurred in the United States. I release the aforewritten .png file and the aforewritten .txt file into the Public Domain. I don't remember exactly what caused me to make said .png and said .txt years ago, but looking at them in 2021-10, they seem incorrect. The math equations expressed by the AMS-LaTeX code seem to be untrue, but I am not sure. Contents of a text file via type and xxd: <pre>H:\0\Documents\!>type "School Math 2015 ...
