Integer a=-16, positive b=2. Give (q,r) with a=bq+r and 0≤r<b, not a negative remainder from truncation toward zero.
G001 — Integer a=-16, positive b=2. Give (q,r) with a=bq+r and 0≤r<b, not a negative remainder from truncation toward zero.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
declared exact integer or rational-representation protocol
After
retain signs,ordered operands and original index order
Conditions: none
Check these finite data with exact integer arithmetic,without floating approximations or a claim to prove all integer-ring axioms.
Rule: integer_arithmetic_scope · Uses: G001
Before
divide a=-16 by positive b=2
After
-16=-8·2+0
Conditions: none
The quotient and remainder satisfy the integer identity and0≤r<b;negative dividends still do not use a negative truncated remainder.
Rule: euclidean_division_witness · Uses: G001, S001
Before
0≤0<2;a=bq+r
After
unique pair(q,r)=(-8,0)
Conditions: none
The difference of two legal remainders has absolute value below b but is an integer multiple of b,so it is0 and the quotient-remainder pair is unique.
Rule: bounded_euclidean_remainder_uniqueness · Uses: G001, S002
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 — 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.(-8, 0)
The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
