Q.1) If A = [3 0 ; 0 -3] and b = [7 2 ; 4 5] then find A + 2B

Step-by-step explanation:

Here:

Therefore, the matrix A + 2B will be:

Therefore:

Matrix: A matrix is a rectangular arrangement of numbers in the form of horizontal and vertical lines.

Horizontal lines are called rows and vertical lines are called columns.

Order of Matrix: A matrix containing x rows and y column has order x × y and it has xy elements.

Different types of matrices:

Row Matrix: This type of matrices have only 1 row. Example:

Column Matrix: This type of matrices have only 1 column. Example:

Square Matrix: In this type of matrix, number of rows and columns are equal. Example:

Zero Matrix: It is a matrix with all elements present is zero. Example:

Identity Matrix: In this type of matrix, diagonal element is 1 and remaining elements are zero. An Identity matrix is always a square matrix. Example:
