However, the Ethiopian Ministry of education provides the Grade 11 Mathematics Textbook for students. Students can download the Grade 11 Mathematics in a PDF file for academic study purposes. In Grades 11 Mathematics courses will be different for natural science and social science stream students. Mathematics at these grade levels should be used as an important instrument for recognising and describing certain fields of objective reality as well as planning and guiding process of development.

Different topics from the history of Mathematics, facts and problems from social practice and other disciplines of science should be discussed and dealt with.
