Each section is explained starting from scratch, with questions, examples, exercises and solutions, all in an interactive way; finally reaching the University level.

You can find the more formal math (mainly using derivatives) integrated throughout the text but only under request; they are on the Show Math buttons so that f you desire to skip the Math, is easier to follow the explanations.
