Let a, b ∈ R. Suppose a > 0. Prove that there is some n ∈ N such that b ∈ [−na, na].

We know there is n ∈ N, b < na , by Theorem 2.67 (Archmidean Property).

Suppose b ≥ 0 we know n ≥ 1 and a > 0 therefore −na < 0 and −na < b then b ∈ [−na, na].

Suppose b < 0: There are two cases:

Case 1: There is n ∈ N such that −na < b then b ∈ [−na, na].

Case 2: b < −na for all n ∈ N...

We know there is n ∈ N, b < na , by Theorem 2.67 (Archmidean Property).

Suppose b ≥ 0 we know n ≥ 1 and a > 0 therefore −na < 0 and −na < b then b ∈ [−na, na].

Suppose b < 0: There are two cases:

Case 1: There is n ∈ N such that −na < b then b ∈ [−na, na].

Case 2: b < −na for all n ∈ N...
