A matrix is a table filled with numbers, usually expressed in capital letters. The important thing about a matrix is that it is not a natural concept, it is a way of representing values, and the calculation of the matrix is also artificially agreed (man-made rules, different methods can be used). First, we need to make it clear that the usual matrix addition and subtraction is defined between two matrices of the same size, and the size must be the same as mxn, so that the matrix addition and subtraction can be defined. The two matrices are added, labeled A+B, and each element of the new matrix obtained is the added value of its corresponding element. Similarly, two matrices of the same size are subtracted and labeled as A-B, each element of the new matrix is the subtracted value of its corresponding element,
