Solve system of equations using inverse
WebYes, matrix A multiplied with it's inverse A-1 (if it has one, and matrix A is a square matrix) will always result in the Identity matrix no matter the order (AA^-1 AND A^ (-1)A will give I, so they are the same). However, matrices (in general) are not commutative. That means that AB (multiplication) is not the same as BA.
