Cambridge IGCSE International Mathematics 2nd edition 2nd Edition, Kindle Edition

I recommend that you buy the Hardcopy instead of this Kindle version.Kindle version is difficult to be used as textbook: CHILDREN MAY GET EYE STRAIN AND HEAD ACHES.

This ebook cannot be zoomed in or out when viewed on Kindle on a Macbook or a mobile phone. The pages are too small to read. The worst thing is I contacted Amazon for support and a case ticket was created, and I have since online chatted with the customer service 4 times in the past 6 days, but was told every time to wait and that I would be updated by email once it is resolved !!! Also, when they created the case, they took the device log from my Kindle, but when I contacted them the second time, I was told they could not find the device log !!!
