Question 5060: Normalized Finite Set Enumeration

Original question and givens

The raw integer list is entries=[9, -9, 0, 9]. Remove duplicates and enumerate every set element increasingly, using [] for the empty set.

• G001 — The raw integer list is entries=[9, -9, 0, 9]. Remove duplicates and enumerate every set element increasingly, using [] for the empty set.

Definition and scope

Use the original question domain, assumptions and cited MKO definitions. This item has second-context mathematical and bilingual review, with the model, answer and every arithmetic step independently recomputed from the original parameters; the source question remains a candidate.

Step-by-step derivation

raw integer list=[9, -9, 0, 9]

extensional set=[-9, 0, 9]

[-9, 0, 9]

one occurrence per element;empty set stays[]

Reverse checks

• S002 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.
• S001 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.

Result

[-9, 0, 9]

The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
