... matches each element of A to just one element of B, and each element of B to just one element of A. (This is not a precise definition; we will see the definition later. But the idea is clear without worrying about how the definition goes.) We say that A and B can be matched if there is a matching be ...

... Any set that can be put in correspondence with ℕ is called countable (ex: E+, ℚ+). Equivalently, any set whose elements can be enumerated in an (infinite) sequence a1,a2, a3,… ...

... Weak König’s Lemma. Every infinite binary branching tree has a path. The second subsystem of Z2 is called W KL0 and contains the axioms of RCA0 plus Weak König’s Lemma. Because the effective version of Weak König’s Lemma fails, W KL0 is strictly stronger than RCA0 . The best intuition for W KL0 ...

Understand that polynomials form a system analogous to the integers, namely, they are closed under the operations of addition, subtraction, and multiplication; add, subtract, and multiply polynomials.
