... idea the integers, however we still can still develop the rationals. For example, when it comes to rings, we would like to avoid the idea of division since many elements don’t have multiplicative inverses, however when dealing with the rationals, it is almost unnatural not to talk about division.

... Theorem 1.9 (P.P. Pálfy). [TCT 4.7, 4.6] Every minimal algebra M with |M | ≥ 3 and having a polynomial operation which depends on more than one variable, is polynomially equivalent with a vector space. Proof. First we explore the consequences of M being minimal and having at least 3 elements. Claim ...

... 7. Let a ∈ Z. If (a + 1)2 − 1 is even, then a is even. Solution: Proof. (contrapositive) Suppose that a is an odd integer. Then a = 2k + 1 for some integer k. So (a + 1)2 − 1 = (2k + 2)2 − 1 = 4k 2 + 8k + 3 = 4k 2 + 8k + 2 + 1 = 2(2k 2 + 4k + 1) + 1. Since 2k 2 + 4k + 1 is an integer, (a + 1)2 − 1 ...
