## 1. An Ordered Generator-Coefficient Weighted Sum

Use a declared finite generator family in a fixed real coordinate space. Preserve generator order, duplicates and its coefficient pairing; all vector dimensions and coefficient counts must match. A span quantifies over all finite linear combinations, not a fixed-arity sample or an undefined infinite series. vectors=[[1, 0], [0, 1], [1, 1]], coefficients=[-12, -3, -2]. Give (original vectors,original coefficients,the coordinate sum).

View answer and explanation([[1, 0], [0, 1], [1, 1]], [-12, -3, -2], [-14, -5])

Scale each supplied vector by its aligned coefficient, then add componentwise. Do not sort or deduplicate generators before weighting. This explicit finite/exact slice does not automatically become a general infinite conclusion. The exact result, retaining the requested order, is ([[1, 0], [0, 1], [1, 1]], [-12, -3, -2], [-14, -5]).

Use a declared finite generator family in a fixed real coordinate space. Preserve generator order, duplicates and its coefficient pairing; all vector dimensions and coefficient counts must match. A span quantifies over all finite linear combinations, not a fixed-arity sample or an undefined infinite series. generator=[2, 4], target=[12, 25]. Give (generator,target,scalar or status,in span?). For a nonzero generator, obtain the candidate scalar from its first nonzero coordinate and retain it even if another coordinate fails. For a zero generator, output any-scalar for a zero target, otherwise does-not-exist. Use exact reduced rational outputs with positive denominators, omitting /1 for integers.

Check all coordinates after choosing the pivot ratio. A zero generator spans only the zero vector, for which every real scalar is a witness. This explicit finite/exact slice does not automatically become a general infinite conclusion. The exact result, retaining the requested order, is ([2, 4], [12, 25], 6, No).
