Cambridge IGCSE Core and Extended Mathematics Fifth edition: Hodder Education Group

This is unusable on a kindle. On Kindle this cannot be zoomed so you have a low resolution image of a page and text is so small that even on a screen with a native resolution of 1920 x 1080 this was unreadable. It becomes impossible to distinguish between subtraction signs and division, to clearly read subscripts and superscripts. The content might be OK but if it is unreadable it is impossible to say.
