Proof Table
# Claim Reason
1 x / x = 1 x / x = 1
2 a ⋅ (x / x) = a ⋅ 1 if x / x = 1, then a ⋅ (x / x) = a ⋅ 1
3 a ⋅ 1 = a a ⋅ 1 = a
4 a ⋅ (x / x) = a if a ⋅ (x / x) = a ⋅ 1 and a ⋅ 1 = a, then a ⋅ (x / x) = a
5 a ⋅ (x / x) = (a ⋅ x) / x a ⋅ (x / x) = (a ⋅ x) / x
6 (a ⋅ x) / x = a if a ⋅ (x / x) = (a ⋅ x) / x and a ⋅ (x / x) = a, then (a ⋅ x) / x = a
