That is true, matrix multiplication is not commutative.
Matrix addition is commutative if the elements in the matrices are themselves commutative.Matrix multiplication is not commutative.

Matrix multiplication is not commutative, meaning that for two matrices A and B, the product AB is generally not equal to BA. Additionally, matrix multiplication is not defined for matrices of incompatible dimensions; for instance, you cannot multiply a 2x3 matrix by a 3x2 matrix without ensuring the inner dimensions match. Lastly, matrix multiplication does not distribute over addition in the same way as scalar multiplication, as the order of operations can affect the result.

The time complexity of the Strassen algorithm for matrix multiplication is O(n2.81).
Matrix multiplication typically refers to an operation which yields a new matrix from a pair of matrices which are already known. This is normally covered in an Algebra class or textbook.

No, a 3x5 matrix cannot be multiplied by another 3x5 matrix. For matrix multiplication to be possible, the number of columns in the first matrix must equal the number of rows in the second matrix. Since a 3x5 matrix has 5 columns and the second 3x5 matrix has 3 rows, multiplication is not defined in this case.

If an identity matrix is the answer to a problem under matrix multiplication, then each of the two matrices is an inverse matrix of the other.
