# Operations of Matrices

In order to add two matrices A and B, they must have the same number of rows and columns. Each element of the first matrix aij is added with the corresponding element of the second matrix bij and the result is an element cij in the same position in the resulting matrix.

# Solving Equation Systems

### Introduction

There are mainly two methods of solving equation systems using matrices. The first uses the inverse matrix of the coefficients of the independent variables and the second converts the coefficients matrix into a unit matrix form.

## Introduction

Laplace Transform is a very useful mathematical tool, mainly used to solve differential equations. It converts the differential equations into algebraic form, which are then easy to be solved and then the solution is inversely converted, using Inverse Laplace Transform, to the form it should initially be.
