A diagonal matrix having equal elements is called a
If A(BC) = (AB)C, then with respect to multiplication this law is called
If a matrix has equal number of columns and rows then it is said to be a
If two matrices A and B have same order and their corresponding elements are equal then it is called
If determinant of a matrix is not equal to zero, then it is said to be
We can subtract two matrices A and B if their
We can add two matrices having real numbers A and B if their
If A and B matrices are of same order and a + b = B + A, this law is known as
Vertically arranged elements in a matrix are called
In matrices, columns are denoted by
A zero matrix ‘O’ of order m-by-n and A + O = O + A = A, then matrix is said to be
Horizontally arranged elements in a matrix is called
A square or a rectangular array of numbers written within square brackets in a definite order in rows and columns is known as
A square matrix in which all elements except at least one element in diagonal are zeros is said to be a
