Question 29644: The Coordinate Additive Inverse and Its Zero Sum

Original question and givens

Use a fixed real coordinate space with nonempty vectors of the same dimension; integer coordinates and scalars are special real instances. Check only the declared coordinate instance, not all abstract vector-space axioms for an arbitrary structure. vector=[6, 1, -15]. Give (vector,componentwise additive inverse,sum,all summed coordinates zero?).

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

source roles = [qf-str22-vectorspace-additive-inverse, vectorspace-additive-inverse]

derived = [[vector, inverse, sum, zero]]

Vector ORIGINAL negate coordinate0 := sub(0, 6)

Vector ORIGINAL negate coordinate0 = -6

Vector ORIGINAL negate coordinate1 := sub(0, 1)

Vector ORIGINAL negate coordinate1 = -1

Vector ORIGINAL negate coordinate2 := sub(0, -15)

Vector ORIGINAL negate coordinate2 = 15

Vector ORIGINAL inverse sum coordinate0 := sum(6, -6)

Vector ORIGINAL inverse sum coordinate0 = 0

Vector ORIGINAL inverse sum coordinate1 := sum(1, -1)

Vector ORIGINAL inverse sum coordinate1 = 0

Vector ORIGINAL inverse sum coordinate2 := sum(-15, 15)

Vector ORIGINAL inverse sum coordinate2 = 0

source roles = [[6, 1, -15]]

derived = [[-6, -1, 15], [0, 0, 0], Yes]

Result

([6, 1, -15], [-6, -1, 15], [0, 0, 0], Yes)

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