Optional Math Grade 9
Optional Math Grade 9 is the collection of all relevant information of the all chapters of Computer Mathematics. The main objective is to provide the study material online for everyone in the digital format freely. We hope that all students will be benefited by Optional Math Grade 9.
The contents are as follows
Chapter 1 : AlgebraIn the Chapter Algebra we are going to learn about the factorization, indices, simplify the algebraic expression and indices, ratio and proportion. The chapter contain mainly the ratio and proportion, indices, linear equation and quadratic equations. 
Chapter 2: Coordinate GeometryIn the Chapter Coordinate Geometry we are going to learn about the triangles, parallelogram, constructions, similarity and circles. The chapter contain the definitions of all the geometrical figures with their numerical problems and solutions. The constructions of these geometrical figures according the the new syllabus are presented by the top facilitators of Nepal.
