Linear equations are the first step into the world of equations.

Linear equations are easy to understand and that's where we start. The next step after linear equations are quadratic equations, then cubic equations and then quadric equations!

Things can get rich, complex and exciting.

The journey starts with the first step that is the linear equations.
