Introduction to matrix math:
Matrices are plural form of matrix which is considered as the key apparatus in the linear algebra. In matrix an item is defined as the element. The matrix entries are denoted by using two subscript in variables. By using the matrix we can denote the linear transformations. The elements in matrix are arranged by rows and columns. Here in this we are going to see general matrix in math.

Matrix in math
Matrix definition:
Matrix is defined as the prearranged set of numbers. Matrix is represented as the rectangular array which consists of numbers arranged in rectangular array. The matrix is represented within the square braces. For example the 2 by 2 matrix is given as,
A = `[[1,2],[4,5]]`
For example the 3 by 3 matrix is given as,
A = `[[8,1,3],[1,2,7],[4,5,6]]`
Properties of matrix:
There are five properties exhibited by the matrices in math. They are,
Property 1:Transpose of matrix.
Property 2: Inverse of matrix.
Property 3: Associative property of matrix.
Property 4: Distributive property of matrix.
Property 5: Commutative properties of matrix.
Types of matrices:
There are some types of matrices in math. They are,
Row matrix:
This is a type of matrix in math which contains only single row. The example of this is given as,
A = [ 5 ]
A = [ 2 6 3 ]
Column matrix:
This type of matrix contains a single column. The example is given as,
C = [ 5 ]
C = `[[1],[2],[3]]`
Zero matrix:
This is a type of matrix in math. In this matrix all the elements present are zero. The zero matrix is given as,
A = `[[0,0],[0,0]]`
Square matrix:
This is a matrix which contains rows and columns in equal number. The example of square matrix is given as,
A = `[[4,8,5],[2,5,6],[1,1,1]]`
Diagonal matrix:
This is considered as the square matrix which contains elements in the matrix as zero except he diagonal elements. The example for diagonal matrix is given as,
B = `[[1,0,0],[0,2,0],[0,0,3]]`
Unit matrix:
In this diagonal matrix all the diagonal elements is one. The unit matrix is given as,
C = `[[1,0,0],[0,1,0],[0,0,1]]`
I have recently faced lot of problem while learning math solver for free, But thank to online resources of math which helped me to learn myself easily on net.
Example problems
Problem 1:
Add the matrices A =`[[2,4],[7,8]]` and B =`[[3,6],[9,10]]`
Solution:
The addition of the matrix A and B is given,
A + B = `[[2,4],[7,8]]``[[3,6],[9,10]]`
= `[[2+3,4+6],[7+9,8+10]]`
= `[[5,10],[16,18]]`
Problem 2:
Multiply the matrix A = `[[1,3],[5,7]]` and B = `[[8,4],[3,2]]`
Solution:
The multiplication of the matrix A and B is given,
A `xx` B = `[[1,3],[5,7]]` `xx` `[[8,4],[3,2]]`
= `[[8+9,4+6],[40+21,20+14]]`
= `[[17,10],[61,34]]`
