In professional data organization and mathematical modeling, a rectangular array of numbers logically arranged in horizontal rows and vertical columns is used to store and manipulate data. Formally classified as a ${}2^{ extrm{nd}}$-order tensor because it has exactly two axes, this structure is known as a:

When a regional data analyst organizes weekly sales figures into horizontal rows for each branch location and vertical columns for each day of the week, they are creating a rectangular array of numbers. In mathematics, this structure—formally defined as a ${}2^{\textrm{nd}}$-order tensor because it has exactly two axes—is known as a ____.

In professional data management and mathematical modeling, structured grids are used to organize information efficiently. Match each term related to these structures with its correct definition or classification.

In professional data management, a matrix is a rectangular array of numbers organized into horizontal rows and vertical columns, and it is formally classified as a ${}2^{ extrm{nd}}$-order tensor because it has exactly two axes.
