No. Matrix addition (or subtraction) is defined only for matrices of the same dimensions.
That is because a cube has 3 dimensions, and a square has 2.That is because a cube has 3 dimensions, and a square has 2.That is because a cube has 3 dimensions, and a square has 2.That is because a cube has 3 dimensions, and a square has 2.
A square matrix A is idempotent if A^2 = A. It's really simple
A 2x4 matrix has 2 rows (horizontal) and 4 columns (vertical). Ex: [1 2 3 4] [5 6 7 8]
An idempotent is a matrix whose square is itself. Specifically, A^{2}=A. For example the 2x2 matrix A= 1 1 0 0 is idempotent.
Well, Im not sure if this is true for all matrices of all sizes, but for a 2x2 square matrix the discriminant is... dis(A) = tr(A)^2 - 4 det(A) The discriminant of matrix A is equal to the square of the trace of matrix A, minus four times the determinant of matrix A. I know this to be true for all 2x2 square matrice, but I have never seen any statement one way or the other for larger matrices. Thus, for matrix A = [ a, b; c, d ] tr(A) = a+d det(A) = ad-bc tr(A)^2 = a^2 + 2ad + d^2 4 det(A) = 4ad - 4bc dis(A) = a^2 - 2ad + 4bc + d^2
no
Yes.
The order of a matrix is another way of saying the dimensions of of a matrix. For a two dimensional matrix, the order could be 2 by 2, or 3 by 3, or 32 by 64.
No.Two matrices A and B can be added or subtracted if and only if they have the same number of rows and columns. That is a 3 x 2 matrix can be added or subtracted only with another 3 x 2 matrix.

It will be a 2 x 5 matrix.

To perform matrix calculations on a Casio fx-991MS calculator, you first need to enter the matrix into the calculator using the matrix mode. Press the "Mode" button, then select "Matrix" mode by pressing the corresponding number key. Next, input the dimensions of the matrix (rows and columns) and enter the values of the matrix. Once the matrix is entered, you can perform operations such as addition, subtraction, multiplication, and finding the determinant or inverse using the matrix menu options.
a squar matrix A is called involutary matrix. if A^2=I
