In a mathematical matrix (similar to a business spreadsheet), we can reorganize or calculate data using specific 'row operations.' Match each mathematical notation to the correct description of the operation it performs.

In a business operations matrix where each row represents a different factory's production data, you are asked to apply the standard matrix row operation denoted as $-2R_3 + R_1$. What exactly does this notation instruct you to do?

True or False: In a corporate logistics matrix where each row tracks a different warehouse's inventory, 'Interchanging rows' is a valid elementary operation that allows you to swap the entire contents of two rows.

In a corporate logistics matrix where Row 3 ($R_3$) tracks fuel costs and Row 1 ($R_1$) tracks maintenance costs, a manager must perform the elementary row operation denoted as ${}-2R_3 + R_1$. Arrange the following steps in the correct order to successfully execute this procedure.
