Cambridge IGCSE and O Level Additional Mathematics Workbook: Hodder Education Group

The description for this publication should highlight that it does not have answers. When I tracked the book down to the Hodder (publisher) website, it would appear that you have to buy an 'Online Teachers Guide' (a snip at £120+ VAT) if you want the answers to questions in the workbook and student book.I would have to surmise that the soon to be released student book is similarly answerless.I also note that if you purchase the student book you do not appear to get access to an e-version which appears shortsighted in this day and age.The workbook itself looks to be well laid out. As a parent/tutor, I would like the reassurance of the answers as would my daughter.
