Throughout our school years, one of the subjects that can cause us the most headaches is mathematics. We're often presented with new and abstract concepts that are somewhat complicated to grasp at first, but I assure you that anyone can grasp all of these things with a little time. I'm a mathematician from the University of La Rioja and earned a master's degree in physics and mathematics from the University of Salamanca. With my help, I guarantee that anyone willing to put in a little effort will be able to tackle this subject without any problems.
