Individuals who are taking the examination.

A matrix where all elements are zero.

The result of multiplying two matrices together.

A matrix that results in a null matrix when multiplied by another matrix, even though neither of them is a null matrix.

The operation that combines two matrices to create a new matrix, where each element is a sum of products.

A matrix with all elements equal to zero.

Adding two matrices is possible if they have the same number of rows and columns. To add them, simply add the corresponding elements.

Multiplying a matrix by a scalar means multiplying each element of the matrix by that scalar value.

The result of adding two matrices, A and B, is another matrix, C, where each element of C is the sum of the corresponding elements of A and B.

The sum of two matrices, A and B, is commutative, meaning A + B = B + A.

The associative property of matrix addition states that (A + B) + C = A + (B + C). Adding three matrices in any order yields the same result.

The number of linearly independent columns in a matrix.

The number of linearly independent rows in a matrix.

In any matrix, the number of linearly independent columns is always equal to the number of linearly independent rows.

Vectors that cannot be expressed as a linear combination of each other.

A mathematical representation of a system of linear equations, used for solving problems in various fields like engineering, physics, and economics.

The maximum possible value of the rank of a matrix 'A' is limited by the smaller dimension of the matrix, which is either the number of rows ('m') or the number of columns ('n').

A square matrix can be created with the same dimensions as matrix A but with all elements equal to zero.

When multiplying matrices, each element in the resulting matrix is determined by summing the products of corresponding elements across a row of the first matrix and a column of the second matrix.

The rank of a matrix is equal to the number of linearly independent rows (or columns) in the matrix. It signifies the 'dimension' of the vector space spanned by the rows or columns of the matrix.
