Mathematics is a science that seeks to study space formats and quantitative relationships. It is a scientific language and an effective tool to depict natural and societal regularities. Mathematical science forms the foundation of natural sciences, technological sciences, etc. It is increasingly exerting its functions in the development of economical sciences, social sciences, and human sciences. I have electrical engineering background with deep knowledge and interest in Mathematics. This class will provide every part of mathematics for secondary schools. For example Algebra foundations: Mathematics I Solving equations & inequalities: Mathematics I Working with units: Mathematics I Linear equations & graphs: Mathematics I Forms of linear equations: Mathematics I Systems of equations: Mathematics I Inequalities (systems & graphs): Mathematics I Functions: Mathematics I Quadratics: Multiplying & factoring: Mathematics II Quadratic functions & equations: Mathematics II Irrational numbers: Mathematics II Complex numbers: Mathematics II Rational exponents and radicals: Mathematics II Polynomial arithmetic: Mathematics III Polynomial factorization: Mathematics III Polynomial division: Mathematics III Polynomial graphs: Mathematics III Logarithms: Mathematics III Transformations of functions: Mathematics III
