Represent a complex number a+b*i by the ordered integer pair [a,b], with i²=−1. Keep the real component first and the imaginary coefficient second; graph appearance supplies no missing values. No complex division or polar form is used here. left=[-7, 2], right=[-2, 1]. Give (left,right,[sum of real parts,sum of imaginary coefficients]).
G001 — Represent a complex number a+b*i by the ordered integer pair [a,b], with i²=−1. Keep the real component first and the imaginary coefficient second; graph appearance supplies no missing values. No complex division or polar form is used here. left=[-7, 2], right=[-2, 1]. Give (left,right,[sum of real parts,sum of imaginary coefficients]).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
source roles = [qf-str22-complex-addition, complex-addition]
After
derived = [[left, right, result]]
Conditions: none
Use this bank exact ordered tuple and hyphenated operation.Rational outputs reduce with positive denominators and OMIT/1 for integers,unlike the preceding legacy bank.Do not change original bilingual snapshots or meaning.
Rule: STR22_exact_interface_and_source_ORDERED_tuple_roles · Uses: G001
Before
Complex ORIGINAL sum coordinate0 := sum(-7, -2)
After
Complex ORIGINAL sum coordinate0 = -9
Conditions: none
Use the ORIGINAL operands exactly,without floating point.Only the declared SOURCE rational operations use their profile;additional integer teaching algebra adds no new input-domain restriction.
Rule: exact_rational_arithmetic · Uses: G001, S001
Before
Complex ORIGINAL sum coordinate1 := sum(2, 1)
After
Complex ORIGINAL sum coordinate1 = 3
Conditions: none
Use the ORIGINAL operands exactly,without floating point.Only the declared SOURCE rational operations use their profile;additional integer teaching algebra adds no new input-domain restriction.
Rule: exact_rational_arithmetic · Uses: G001, S002
Before
source roles = [complex-addition, [-7, 2], [-2, 1]]
After
derived = [[-9, 3]]
Conditions: none
From(a+bi)±(c+di)=(a±c)+(b±d)i,combine matching components.Real stays first;subtraction is left-right,not an absolute difference.

S004 · premise_and_result_audit — Reverse-check every ORIGINAL coordinate/table entry/alignment and strict premise,not just the final answer.Keep finite candidates,general reasoning,formal proof and publication responsibilities distinct.S003 · premise_and_result_audit — Recompute Complex ORIGINAL sum coordinate1 with exact rational arithmetic, not rounded decimals.S002 · premise_and_result_audit — Recompute Complex ORIGINAL sum coordinate0 with exact rational arithmetic, not rounded decimals.S001 · premise_and_result_audit — Reverse-check every ORIGINAL coordinate/table entry/alignment and strict premise,not just the final answer.Keep finite candidates,general reasoning,formal proof and publication responsibilities distinct.([-7, 2], [-2, 1], [-9, 3])
The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
