WebWe can multiply to see that A B=I_2 AB = I 2 and BA=I_2 B A = I 2. [I'd like to see this, please!] This means that A A and B B are multiplicative inverses. However, as we will see, not all matrices have multiplicative inverses. This is one place where the properties of real numbers differ from the properties of matrices! Sort by: Top Voted WebDeterminant is calculated by reducing a matrix to row echelon form and multiplying its main diagonal elements. Have questions? Read the instructions.
