Waiting for Linux Mint Adrien to be released and taking a short break from Totten (YoAdrian) to bugfix a .py calculator file

This was interesting and educational. I learned about financial calculators and what "PM", "I/Y", "P/Y", "PMT", "N", etc... means. https://forums.linuxmint.com/viewtopic.php?t=475593 If it gets deleted, their youtube link is https://www.youtube.com/watch?v=TCUhBpNMi_o My comments were: 1) Clicking "Ans" repeats the answer for negative numbers. (example: 13-54, Ans, Ans, Ans) (Same in other View areas with the same Ans button). 2) When there are longer calculations, the window expands but doesn't default back unless history is cleared. Also, there is no way to resize it smaller than it expanded. To recreate it, just do a math problem that fills past the available space. 3) In the calculator I usually use when I duplicate something I get "Malformed expression". In the Xcalculator, I get "Calculation Error" if there is an accidental double click of something like sin, cos, tan, etc... 4) When I go to type numbers, the cursor jumps to the left instead of staying on the right. 5) Another aspect to 4 is let's say you type 1234556789, and you see you goofed. If you try to remove one of the 5's it removes the 9, whatever is on the right instead of a 5.
