Use an exact finite rational-point slice embedded in R, without approximate decimals or a completeness claim. Ordered points=[-12/2, 0/1, 13/3]. Give (increasing distinct points, minimum lo, maximum hi, hi−lo); the containing interval is [lo,hi], not the point set’s topological closure.
G001 — Use an exact finite rational-point slice embedded in R, without approximate decimals or a completeness claim. Ordered points=[-12/2, 0/1, 13/3]. Give (increasing distinct points, minimum lo, maximum hi, hi−lo); the containing interval is [lo,hi], not the point set’s topological closure.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.
Before
explicit rational points embedded in the real line
After
exact finite order and distance data,not real completeness or irrational classification
Conditions: none
Use exact rational values for this finite slice of the real line,without rounded decimals or claims about real completeness or classification of irrationals.
Rule: rational_real_slice_scope · Uses: G001
Before
[[-12, 2], [0, 1], [13, 3]]
After
[-6/1, 0/1, 13/3]
Conditions: none
Sort and deduplicate by rational value,not fraction strings;0/−2 and0/3 represent the same point0.
Rule: rational_point_numeric_normalization · Uses: G001, S001
Before
smallest containing interval width := sub(13/3, -6)
After
smallest containing interval width = 31/3
Conditions: none
Rightmost minus leftmost point gives the nonnegative interval width.
Rule: exact_rational_arithmetic · Uses: G001, S002
Before
all points between -6 and 13/3
After
smallest containing closed interval=[-6,13/3]
Conditions: none
Every containing closed interval must include the smallest and largest points,hence this interval is minimal.This is not a claim that topological closure fills the gaps of a finite point set.
Rule: containing_interval_not_topological_closure · Uses: G001, S003
S004 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.S003 · premise_and_result_audit — Recompute smallest containing interval width with exact rational arithmetic, not rounded decimals.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.([-6/1, 0/1, 13/3], -6/1, 13/3, 31/3)
The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
