IDZ Ryabushko 1.1 Option 12 is a training task in linear algebra, which includes two tasks.

The first task is to find the minors and algebraic complements of the determinant and calculate its value in three ways: expansion over the elements of the i-th row, expansion over the elements of the j-th column and first obtaining zeros in the i-th row for i = 1 and j = 2.

The second task consists of several points. For two given matrices A and B, you need to find their product (AB and BA), the inverse matrix A–1, the product of matrix A and its inverse matrix (AA–1) and the product of the inverse matrix A–1 and matrix A (A–1A) .
