Now I'm begin to translate new book for grade 9 to preparing for outstanding student test both province and nation test. It's a new book full of good exercise and how to solve it with a good solution ^_^
This book, not like the old version one that just have exercise, for this one, i have added more strategy, keys and important formula to review and make you easy to understand hot to solve the problems.
Hope this one can make you have fun with maths and like to study maths than before. And now let enjoy the first 12 pages in Khmer version as the review of this book ^_^.
