Mathematics Essential Units 1&2 is a new edition that has been carefully written to prepare students for success in the Mathematics Essential Units 1&2 ATAR course. New sections have been added to several chapters and some optional material has been trimmed to make the coverage of the Maths Essential Units 1&2 syllabus clearer for teachers and students. The Interactive Textbook – complimentary with purchase of the print book – has been updated with a number of new features, and the Online Teaching Suite has been expanded to give teachers even more support.
