Natural Sciences are fundamental to understanding how life works. Chemistry is the structural basis of life. It all comes down to atoms associating with each other to be what we are and what we see (and even what we don't see). Understanding Chemistry well will allow you to be a professional with great opportunities that creates and develops the advancement of society. I also provide great support to reinforce those mathematical knowledge that are difficult for us to understand. Mathematics is the expression through numbers of the laws that govern the universe.
