Expert Solution
Step 1: Formulae for Axioms

The Peano Axioms are usually formulated as follows:

  1. 0 is a natural number.
  2. For every natural number n, n = n. (Reflexivity)
  3. For all natural numbers m and n, if m = n, then n = m. (Symmetry)
  4. For all natural numbers l, m, and n, if l = m and m = n, then l = n. (Transitivity)
  5. For all natural numbers m and n, if m = n, then m + 1 = n + 1.
  6. For all natural numbers m and n, if m + 1 = n + 1, then m = n.
  7. For all natural numbers m, m + 1 is a natural number.
  8. For every natural number n, n + 1 ≠ 0.
  9. For all natural numbers m and n, if m + 1 = n + 1, then m = n implies that m = n.
  10. (Induction Axiom) If S is a set of natural numbers such that 0 is in S, and for every natural number n, if n is in S, then n + 1 is in S, then S contains all natural numbers.
