Over R, A=[[-2], [0], [2]] and B=[[-7], [-6], [-5]] have the same dimensions. Find A+B as a nested list of rows.
G001 — Over R, A=[[-2], [0], [2]] and B=[[-7], [-6], [-5]] have the same dimensions. Find A+B as a nested list of rows.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

After
derived = [[nested_ROW_matrix]]
Conditions: none
MOD25 uses LOCAL hyphens/named domains,legacy matrices underscores/reals;BASE logic acquires no domain/op.Output tuples,matrices,numeric fields and fraction texts follow THIS source,not a universal/1 rule.Retain originals/English/AST/status.

Conditions: none
THIS bank allows1..5 by1..5 matrices,not the R64 2×2 restriction.Type EVERY raw SAFE cell,including unused shape/entry cells.Keep original row order.
