In this application you will learn to learn to solve linear and quadratic equations. We develop step by step the solution process of each equation. We start with natural numbers, raising the level of learning to whole numbers and concluding with fractional numbers. You can follow the development of the solution of the equation that you want to solve to learn the procedure, solve an equation in your notebook and compare the result in the application, so you will know if you did it correctly or what you were missing. In this way, you will master the procedure preparing you to solve more complex equations.
