Original question and givens

In the classical integer context, consider x≤-1 with assignment=-7. Give (is the sentence closed?, its bound truth value or open, substitution difference or not-applicable).

  • G001 — In the classical integer context, consider x≤-1 with assignment=-7. Give (is the sentence closed?, its bound truth value or open, substitution difference or not-applicable).

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

S001 · implies

Before

classical integer formulas with explicit binding/data

After

a truth verdict is not a delivered general proof object

Conditions: none

A false closed statement is still a proposition.These finite substitutions and comparison witnesses do not promote a truth label to a general formal proof or completeness of arbitrary inference rules.

Step identifiers and dependencies

Rule: proposition_truth_and_proof_scope · Uses: G001

S002 · calculation

Before

bound integer comparison difference := sub(-7, -1)

After

bound integer comparison difference = -6

Conditions: none

Substitute only after receiving an integer binding;the difference is x minus the threshold.

Step identifiers and dependencies

Rule: exact_rational_arithmetic · Uses: G001, S001

S003 · implies

Before

x=-7;threshold=-1;x−threshold=-6

After

bound statement truth=True

Conditions: none

A bound0 is a valid value too.The condition difference≤0 is exactly x≤threshold;programming-language truthiness is not mathematical binding.

Step identifiers and dependencies

Rule: bound_integer_formula_verdict · Uses: G001, S002

Reverse checks

  • S003 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.
  • S002 · premise_and_result_audit — Recompute bound integer comparison difference with exact rational arithmetic, not rounded decimals.
  • S001 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.

Result

(Yes, True, -6)

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