This book is not for advanced students. Rather it is suitable for people who want to revise the math they learned at school, or just to get some knowledge of the Math. It is an easy book to follow, not made too difficult like other math books. Problems are set after each section and the answers are, of course , given. It includes many sections of math, graphs,, indices, equations, inequalities and others.  I would recommend it if you want to learn basic math, perhaps with the thought of further study , like myself.  A knowledge of Math is a great help in understanding everyday problems one may meet.
