10/29/19 College Algebra Has Gotten Harder? (Part 2)

    We worked on the third quiz until almost midnight Saturday.  Luckily, YouTube really will show you anything.  I started on Google, trying to figure out what this Matrix Math was.  It is really a way to find answers for systems of equations, much like the elimination or substitution, but this really requires a lot of work.  I had to learn how to add and what scalars were and that the matrices matter as far as which one sits in front of the other, meaning A+B does not always equal B+A.  There is also no way to do division, but there is a way to figure out the inverse of a matrix and then multiply by this, effectively this becomes a way to divide.  We filled page after page, but I think I figured out most of the nuances involved and I did enjoy getting them done after I knew what I was doing, but some of these problems took like 30 minutes apiece.
    Javalina kept saying thanks Dad, I'll just submit what I have and that will be fine.  That pissed me off because he might be willing to settle, I never have.  I told him "no, I squeeze every point out of an assignment, I don't half ass."  We only stopped for food, and before we knew it was Sunday morning.  I usually get up early to mess around on the computer, but all that math work left me beat.  I didn't get up Sunday afternoon until 1:00pm and it was immediately back to it.  We did one homework assignment which he kept complaining that the quizzes account for 80% of the grade and HW only accounts for 10%.  I said you are doing all of it, so you might as well just keep going.  We finished this and I think I walked off to see what Wife was doing in the guest room. I jumped on the bed and fell asleep.  Javalina came after me to continue and it was just more and more math.
    We finally got to a stopping point around 8:00pm Sunday night when we had finished the four quizzes for the six weeks period and had a 100, 86, 85 and 85, for an 89 average.  Not bad, considering I was learning with him and from the computer.  He had about 8 HW assignments also and I helped him with the one.  He said he had done two already and tonight I told him to do two more.  He sent me pics of his progress, so hopefully he gets to tomorrow with only a couple more HW assignments to do.  This will be the last time he blindsides us because we will be communicating with his teacher much more regularly, fat little liar.
