augmented matricies

Arguably the reason why high school students commit suicide, and the most difficult concept of Algebra 2. A complete waste of time, as there are various other methods of solving matrices that don't involve half-hour long porcesses that are very liable to error.

Test on augmented matricies: Augment the Matrix:

( 2 4 5 | 5 )
( 1 3 3 | 2 )
( 2 4 6 | 2 )

Student: "OH LORD JESUS HAVE MERCY!" /uses Kramer's rule anyway

matricide 

Matricide is the act of killing one's mother.

In the movie Psycho Norman Bates committed matricide by killing his own mother because she was constantly meddling, screaming and calling all his girlfriends sluts and dirty. What was even more freaky, is that after he buried her, he began to miss her, so he dug her back up again and pretended that she was still alive by dressing up as her and pretending that he was her. Norman also kept her corpse fresh with taxidermy and whenever he was let out of the nuthouse he would constantly dig his mother up to be with her.
