Rule of Sarrus
text:
In matrix theory, the rule of Sarrus is a mnemonic device for computing the determinant of a 3 × 3 matrix named after the French mathematician Pierre Frédéric Sarrus. Consider a 3 × 3 matrix then its determinant can be computed by the following scheme. Write out the first two columns of the matrix to the right of the third column, giving five columns in a row. Then add the products of the diagonals going from top to bottom (solid) and subtract the products of the diagonals going from bottom to t
