How are new units added?

Before each unit finishes, I will add all the unit notes from my study sheet here. I have math class until the semester ends, so there will be around 4-8 units by the end of semester (depending on how many days each unit takes to complete).

What kind of math notes are featured here?

Some are from my math notes which I take during class while others are from my personal study sheet. Everything is double-checked with online research. Furthermore, old notes from archived units may be updated every once in a while depending whether or not I missed some important concepts. The Math Study website has just been released so there will be tons of new updates content-wise, especially for math unit notes.
