... 1–18 Multiplying by b, pub + abv = b. But now p | ab =⇒ p | b.  Now suppose a is neither a unit nor 0; and < /b> suppose that a is not expressible as a product of primes. Then a is reducible, by the Lemma above: ... b, pxb + aby = b. But p | pxb and < /b> p | aby (since p | ab). Hence p | b.  Theorem 1.3 Suppose n ∈ N, n > 0. Then n is expressible as a product of prime numb...

... A possibly equal to B) , and < /b> A  B means that A is a proper subset of B (i.e., A ⊆ B but A = B) . Further, A ∪ B denotes the union of A and < /b> B, A ∩ B the intersection of A and < /b> B, and < /b> A \ B the set ... dividing a by b. It is clear that b | a if and < /b> only if a mod b = 0. Dividing both sides of the equation a = bq + r by b, we obtain a /b...
