Algebra – Grades 9 & 10

High School Algebra (Grade 9-10) assumes that students are already familiar with the basic concepts which were covered in Grade 6-8 level courses. The following topics are covered in Grade 9-10 level courses: Expansion and Factorisation, Set Theory, Algebraic Fractions, Exponents and Surds, Functions (different levels of difficulty), Quadratic Equations and Functions,Logarithms. The students will have access to large number of assignments which will test their understanding of the concepts and help them master these topics.
