Simone Malacrida 
Handbook of Elementary Mathematics 

This book lays the foundations of mathematics, starting with logic and elementary operations and moving on to topics such as trigonometry, complex numbers, matrix and vector notations, while addressing plane, solid and analytic geometry, as well as the rudiments of combinatorial and numerical calculus.
Such topics are necessary for the understanding of mathematical analysis and all modern developments, while providing a useful extension of knowledge for an initial mathematical description of the natural phenomena around us.
