Detailed Solution

Let's analyze the given axioms:

(i) Things which are equal to the same thing are equal to one another. Comment: This is known as the transitive property of equality. It essentially states that if A = B and B = C, then A = C. This axiom seems self-consistent.

(ii) If equals are added to equals, the wholes are equal. Comment: This axiom is a basic property of arithmetic. If A = B and C = D, then A + C = B + D. This axiom is also self-consistent.

(iii) Things which are double of the same thing are equal to one another. Comment: This means if you double the same value, you get the same result. For instance, if A = B, then 2A = 2B. This is another basic arithmetic principle.

All three are consistent.
