- Late hw submissions delay the process of grading and posting. Please do not submit late unless you get permission to do so. Unauthorized late submissions will be subject to grade adjustments.

- § is the section sign, for example § 1.9 is the first chapter section 9.

- What is the difference between notations A:=B and A=:B? You may see these rarely in the notes. A:=B means A is defined to be equal to B. A=:B means B is defined to be equal to A. In both cases, A=B. But := and =: tell us whether B existed first or A existed first. This is a kind of a chicken and egg issue. However the notation can be helpful in exposition.
