**4. What are some definitions of key terms in the algebra of matrices?**

A matrix is a set of real or complex numbers or functions arranged in a rectangular manner. Elements of the Matrix are individual items in the equation. Rows are the horizontal line elements and columns are the vertical line elements. The order of a matrix is determined by the number of rows and columns it has. Different types of matrices are as follows: Column Matrix, Row Matrix, Square Matrix, Diagonal Matrix and Identity Matrix. Operations on Matrices can either be addition, subtraction or multiplication. We get a transpose for a matrix by exchanging its rows with its columns.

**5. What are some applications of Matrices?**

The uses of matrices are many. They are compact methods of solving linear equations. They can be used to represent coefficients in the linear equation system too. Apart from these fundamentals, matrices are also used in -

Cryptography

Matrix notations and operations are used in electronic spreadsheets

Used in systems such as business and sciences as an aid in budgeting, cost estimations, sales projections, analysis of experiment results, data tabulation, etc

Also found to be used in branches such as genetics, economics and even modern psychology

Can be used in physics to represent equations in magnification, reflection, rotation, etc.

Used in 3D Maths to describe spaces between two coordinates
