Determinant of a 3x3 Matrix

Videos, worksheets, games and acivities to help Algebra students learn how to find the determinant of a 3x3 matrix.

3x3 Determinant :
Methods for computing a 3x3 determinant are important and are used when defining the cross product. Finding a 3x3 determinant is not as computationally heavy as finding the determinant of a larger square matrix. However, finding this determinant is more complicated than finding a 2x2 determinant. Using methods for simplifying determinants through row operations can make finding the 3x3 determinant much simpler.
