Intro To Matrices Article Matrices Khan Academy A matrix with 2 columns can be multiplied by any matrix with 2 rows. (an easy way to determine this is to write out each matrix's rows x columns, and if the numbers on the inside are the same, they can be multiplied. e.g. 2 x 3 times 3 x 3. these matrices may be multiplied by each other to create a 2 x 3 matrix.). Learn what matrices are and about their various uses: solving systems of equations, transforming shapes and vectors, and representing real world situations. learn how to add, subtract, and multiply matrices, and find the inverses of matrices.
