Shame of mathematics (or it's usage):
In an equation or matrix dishing out debt [negative number and mathematical functions] - there is only a few ways to get out of that... instantly...
none are great exists but everything else prolongs it with dubious cure...

So as some games go (even chess) they are worth solving... but for deliberate man-made mathematical made trap it does make you/I/we ashamed of how mathematics is used more than less.
