Modeling with Matrices
A matrix with m rows and n columns has the dimensions of m x n

Transposing a Matrix – Switch the rows and columns Addition and Subtraction Add or subtract the corresponding values from each matrix. You can only do this with matrices that are the same size Multiply by a Scalar Multiply the value into every entry  like distributive property
