I studied Maths about 22 years ago and I needed to study it again. Some answers at the back are wrong. For the advanced questions I would have like the author to give us a clue to solving it. That way you are not going about the solution the wrong way. I have so far not been able to answer 1 question out of 4 chapters. I am doing OK so far apart from this one question. I have enjoyed working through it to though and enjoying it.
It arrived quicker than expected even when using the normal free delivery option. The book itself is a very good textbook though one should not purchase it if one plans to teach themselves all of the content. The book is more suited to be an aid to classroom based learning and it accomplished this very well.
