There is no partial credit when it comes to Explosives and Quantifiers.
The nifty-diffty Primer on cardinality.
- While not required for our course, the
Primer on Polynomials
has further information on Algebraic Numbers, for the Curious Ambitious Student.

also has some of the abbrevs that I use in grading.
Our Class-A was entertaining.
Relevant to the tiling question is the cool
It has a nice question about tilability-of-unions.
One question on Home-A

Pictures of Lmino Tilings (txt).
for the first part of (A3), were these graph-papers:
Being a visual exam, there is an induction-proof essay, with images, giving a
soln to all Zoid-tiling problems (PDF).
We also have
pictures of 3-mino tiling (txt).
Finally, students in a previous SeLo class generated this picture of
zoid-tiling of a 3^k triangle, when k =3= 0,
as well as a
zoid-tiling of a 3^k triangle, when k =3= ±1.

SeLo quizzes so far (pdf),
- We use two, free, online texts:
Book of Proof,
by Richard Hammack.
Transition to Higher Mathematics: Structure and Proof,
Bob A. Dumas
John E. McCarthy.
- Does Zero = One? (pdf).
Here are some
proofs poofs about which
you can post to our Archive.
- The Math-Greek alphabet (pdf).
- The famous On-line Encyclopedia of Integer Sequences, and
W: OEIS history, and a
video with a challenge at the end.

From our Teaching Page, have
Lightning-bolt algorithm (pdf)
[pages 1-3. You are not responsible for pages 4,5];
practice sheet for LBolt (pdf)
[print on paper and work through several examples];
Algorithms in Number Theory (pdf)
[you are responsible just for the Iterated Lightning-bolt part, page 1]
- A std proof of the
Inclusion-Exclusion principle (pdf), together
with Candy-Store, Derangement and Stirling-number examples.
- Exams/notes from previous incarnations:

It has my schedule,
