Mathematics is for all

Today I was able to prove once again that mathematics is not just for a few. Challenging Brainteasers taught me how mathematics are not only fun but accesible to all. Besides enjoyig solving many of these brainteasers it provided me with many fine tools to work with my own children and students problems that I previously thought were imposible. A big clap for Recamán.

Wonderful for the classroom

I have found this fine collection of puzzles a wonderful source to stimulate my mathematics students. There are problems and puzzles of all levels of difficulty, and on a wide range of topics. Some are classics in a revised form but lots are new to me. All are great fun.

Recamán Santos is a real brain teaser

I've been a student and a disciple of Professor Recamán for several years. Needless to say that his work, like all his life accomplishments are an example to be followed. Bright, witty, irreverent, with a passion for life and an outstanding sense of humour, he is definitely a magister teaser.

Having fun with numbers and logic

It is always rewarding to find that you do have a knowledge of mathematics and logic you have not been aware of. This wonderful little book offers puzzles and enigmas you can solve applying your mathematical abilities. It is clever, interesting and above all fun. Its a teaser and a great companion to idle hours. Great!
