It is one of the oldest concepts in mathematics.There were traces in the 2nd and 4th century BC.The concepts were developed during the 17th century.When the mathematicians tried to solve the problem with multiple simultaneous linear equations they needed matrices and determinants.Some of the clay tablets created with the matrices that are still preserved are from the Babylonians era.

This is used in the normal life.The matrices can be used to solve complex problems using a computer.There are predictions and model developments using matrices.The word matrix was invented by a lawyer and a mathematician in the 17th century.The concept of matrix was used in a powerful way by the concepts of mathematics.

In relation to organised cars in a parking area coconut trees in a farm land and storage of boxes in a storage area we can see matrices in common practise.The basis of the term is the quadratic form.This was created by Gauss in the 17th century.The idea of determinants was expanded by another mathematician.The coefficients of the linear equation can be written with matrices.

In data is represented in excel spread sheet as a matrices and it is used in almost all corporates and educational institutions.A lot of the dashboards developed for management decision making and operational analysis are in a matrices format with rows and columns.A table with years in the columns and states in the rows can be used to show the population of India over the past 10 years.There are rows and columns in the matrix.The brackets are usually placed over the rows and columns to indicate that a matrix has been formed.

The size of the matrices is determined by the number of rows and columns in them.The size of the matrices is determined by the number of rows and columns.The matrices that have a single row are called row matrices.Column matrices are the matrices that only have one column.The zero matrices are a type of matrices where the elements are not 0.

It's also called a null matrix.The square matrices have the same number of row elements and column elements.The principal diagonal is represented by elements that fall in the diagonal line.The principal diagonal has different names.It's also known as main diagonal or leading diagonal elements.

The rest of the elements are all zero in unit matrix.All elements have a value of 1 in the diagonal elements.A triangular matrix is a type of matrix found in the square matrix.The triangular matrix is called that if all the elements in the bottom of the diagonal are zero.If all the elements in the matrices are equal we can say that the two matrices are equal.

If any of the elements are not the same or not in the same order they are called unequal matrices.Adding multiplication and subtracting are some of the operations we can do.The division of two matrices is impossible.There are certain requirements to be satisfied before we perform the operations.If we have to multiplication all the elements of the matrices with the same element then we need to use a constant.

If both the matrices have the same number of rows and columns we can add and subtract them.The A+B of each of the elements of the matrices is indicated by the addition of matrix A with matrix B.The A-B of the elements of the matrices are indicated by the subtraction of Matrix A with matrix B.If the number of rows and columns of one matrix is the same as the number of rows and columns in the other matrix we need to add or subtract them.We need to mention in the result that an addition or subtraction is not possible if not.
