A few possible additions to the symbols and functions in Chapter 1 (note I took it with Bai, so we may have covered different topics/used different notation!):
In 1.1.1 or 1.1.3, "A x B" (Cartesian product of A and B) and "A^2" (the Cartesian product of A with itself) are important notions when discussing mathematical relations.
In 1.1.3, "U" (possibly in a different font?) is often used to represent the universal set
In 1.1.3, the notation "aRb" was used in my class to represent "(a, b) \in R"
In 1.1.6, the first definition can be clarified "sum of the first n integers"
In 1.1.6, the same
In 1.1.6, there is also common notation to write "\sum{1 \leq i \leq n}" or, more generally, "\sum{R(i)}" for arbitrary requirements on i.
The first identity in 1.2.5 is commonly called the "inclusion-exclusion principle"
Most of these are just additions to make so students with other professors and seeing a different set of notations don't get confused! I will work on this after Issue #8 is resolved.
