Ian Jacques in this 8th edition of Mathematics for Economics and Business has produced a useful work, most specifically for students who did not perform well in Mathematics in High School but still want to conduct studies in Economics and Business. Ian Jacques does not adopt the professorial tone of the majority of university lecturers but levels with these mathematics-challenged students by using the conversational level language and more so in his rectangular frame Advice placed at the bottom of the various Sections of the text. He starts with Linear equations (negative numbers,expressions,brackets) and right in this first chapter addresses the Supply and Demand analysis of Economics.. Ian Jacques' work gives a second chance to students who suffered through bad teaching of Mathematics in High School but still want a career or training in Economics and Business. Go for it !
The book has lots of example exercises with very good step-by-step explanations but this edition (unlike the previous ones) is marred with typos and the register of solutions at the end seems to have just been copied and pasted from the previous edition even though some of the questions were changed. This can be a real problem in that you will end up trying and trying to solve an exercise and in the end it will turn out that not your solution, but the one provided at the end of the book is wrong. I would recommend one of the older editions.
Concepts are explained well and are useful for all ability levels. While it may be deemed 'over simplistic' the simplified explanation of techniques leaves no potential for not understanding.
Why 3 stars? Far too many of the answers in the back of the book are missing a minus sign etc. seemingly through carelessness. This throws you off a little until you realise you can calculated the problems better than the person writing the answers and decide not to bother looking at them defeating the point of an answers section.
5/5 for explanation 1/5 for answers
Conclusion: Get the book for explanations and another for questions or just don't bother getting it
Whilst there is good explanation and clear presentation, a LOT of typos.. Something VERY unhelpful in a maths textbook with applications you're unfamilar with. I thought I was going crazy and misreading economic notation but glad to see that others are having the same problem. Simply unacceptable for a textbook this price.
I have been using this book for my degree course (first year) and have found some very important errors within the book. such as formulas are written the wrong way round, so the right answer can be is impossible to find if you are learning these methods for the first time. Also some of the practice questions have the wrong answers. By version 7 of the book you would have thought most errors had been eliminated by now.
