 That an consistency, because the two `nth`axioms are contradictory
 
-The completeness is when we have enough axioms for our abstract type
+The completeness is when we have enough axioms for our abstract type :
+1. **Completeness**: Axioms should provide a complete and unambiguous specification of the ADT's behavior. This means that they should cover all possible scenarios and outcomes for the ADT's operations. Users of the ADT should be able to rely on these axioms to understand how the ADT behaves in different situations.
+
+2. **Consistency**: Axioms should be consistent with each other and with the intended behavior of the ADT. This means that the axioms should not contradict each other, and they should accurately reflect the expected behavior of the ADT's operations. Inconsistent axioms can lead to confusion and incorrect usage of the ADT.

 To use partial operations we have to create some preconditions
