my journal 3

All right. Let's get started again. This time with a stricter filter (only posts from contacts):


I'll keep writing the same things I wrote on my previous journals, "my journal" and "my journal 2". Go there if you need information about something I am referring to.

Done with my daily math exercises at khanacademy.org:

Usual dose of daily math:


This one below wasn't easy:
Functions 3 | Khan Academy

It takes focus on top of knowledge. I did almost 10 exercises right, then got one wrong, and it made me go back ten exercises again, then made one mistake again, and had to go back again... it's almost impossible to get a whole set right, because by the time you're at the last exercise you're exhausted. Also, you need to do them the other way around and start from the inner functions.

For a while, I am not going to watch new videos and embark on new topics, since I am just tackling the review exercises. This before finishing all the exercises.

Enjoyed that Functions question. Bit rusty.......Ironic as I am studying mathematical sciences at the minute. keep it going.

Yes, thanks for the feedback. Hopefully I'll get to a higher level one day (which will enable me to understand portfolio theory), but first I have to build solid foundations, and khan academy is really good at that, and at making you get in touch with math again, after school made you dislike it.

52 to go:



Probably done for the day.

Glad your journal is back up and running.

Thanks. I had thought there were a few silent readers appreciating my journal. Thanks for letting me know.

Daily math done:



They came up with 4 new exercises, so I've done many, but I still have 49 exercises to go. 80% of work done. After this, I will have very solid foundations (and what's most important, I will have confidence in my math skills), but still not enough to tackle portfolio theory. I have plenty of time in my hands anyway, since there's no capital in sight. And this is the best investment of my time.
