Best sites to learn and practice mental math skills?
Hi, what are the best sites to learn and practice mental maths skills?
For example 4328*1142, 2758/113, 112^12, square root of 7056
This is the kind of difficulty I'm looking to learn and practice.
Look through this thread https://www.wallstreetoasis.com/forums/mental-math-help-resources
the secrets of mental math, best book I ever bought. Fun and easy to read
Who's the author?

Anybody have a pdf link to the trachtenberg book, or another idea for a way to get better at mental math for the prop firms.

Other free mental math resources:
Wikibooks: http://en.wikibooks.org/wiki/Mental_Math Ars Calcula: http://arscalcula.com/
http://arithmetic.lemo.education/. Its free, it works, its that simple. I would say that easy and medium are enough for 99% of all interviews, hard is a bit mad.
United Kingdom Mathematics Trust tests at Senior - Hard level for example at http://www.mathster.com/challenge/ are challenging, also psychometric reasoning tests https://www.wikijob.co.uk/aptitude-tests-home, can train numerical and related reasoning skills also, hope this helps
