WebJul 7, 2024 · A series of studies was conducted by Stevenson and his colleagues to explore what determines mathematics achievement by comparing American, Japanese and Taiwanese students, with participants from kindergarten to high school. An early study focused on a cognitive issue, comparing digit memory in Chinese and English. WebThe reduced row echelon form of the matrix is the identity matrix I 2, so its determinant is 1. The second-last step in the row reduction was a row replacement, so the second-final matrix also has determinant 1. The previous step in the row reduction was a row scaling by − 1 / 7; since (the determinant of the second matrix times − 1 / 7) is 1, the determinant of the …
