First order of business today was Algebra. Learned about the Rational Zero theorem, which is really complicated so I won’t be putting it here, but to put it simply it’s purpose is to test different zeroes of a polynomial function using synthetic substitution.


Next up, Economics. I learned about barriers to international trade, for example, tariffs. Tariffs are taxes placed on imported goods, and there are different kinds. Protective tariffs are tariffs that are high in order to protect less efficient domestic industries. Revenue tariffs are done in order to generate profit.

There are also quotas, where only a certain amount of a domestic good can be imported, and are usually used to keep domestic prices high.


Lastly, Programming. I learned about I2C, A bus in the programming sense that is mainly used for communication within a board. I2C really means Inter-Integrated Circuit, which is rather self explanatory. Interestingly, while the format is free to use, it is not free to get the addresses needed to use it.
