Hi GMATters,
Properties of Numbers questions are a killer for a lot of my clients so I've put together a 23-page document as an easy reference for them to use.
It's designed to be an easy read and to tackle as many of the major concepts tested as possible.
This is most certainly a work in progress, so I'd love to have any feedback that comes to mind. Especially concepts you think aren't clear/missing/etc.
Looking forward to hearing what you think:)
Rowan
