No. Addition is only defined for matrices of the same size. Multiplication is only defined for matrices where the first matrix has the same number of columns as the second matrix has rows. It is entirely possible to have matrices that you can add, but not multiply (any pair of 3×2 matrices, for instance), and pairs of matrices that you can multiply, but not add (a 2×3 matrix and a 3×2 matrix).

No.
In Addition and Subtraction, both matrices must have the same number of numbers in them.
Multiplication of two matrices iscan only occur if the number of columns of the left matrix is the same as the number of rows of the right matrix.

for addition and substractions, the matrices have to be exact same size, that is correspponding number of rows and columns should be equal.
but for multiplication of matrices, the number of colomns of the first matrix should equals the number of rows in the second matrix.
Remember the order of matrix,,after seeing the above conditions,don;t interchange the matrices in their places,u wont be able to multiply until and unless they are sqaure matrices of same order

Only if they have the same order
i e they both have the same number of rows and columns

No, they have to be compatible sizes.
