For anyone that's confused, matrix composition is just matrix multiplication in a specific order. For example, A º B isn't equal to B º A.

Sal defines what it means to add or subtract matrices. He shows a few examples and discusses some important properties of matrix addition and subtraction.

The dimensions of a matrix give the number of rows and columns of the matrix in that order. Since matrix A has 2 rows and 3 columns, it is called a 2 × 3 matrix.
