10 steps: (1) Matrix: a rectangular array of numbers. 2×3 means 2 rows, 3 columns. (2) Addition: add corresponding entries (same dimensions required). (3) Scalar multiplication: multiply every entry by the scalar. (4) MATRIX MULTIPLICATION: (m×n)·(n×p) = (m×p). Inner dimensions must match. (5) How t
