One equals zero and other mathematical surprises is a collection of paradoxes' fallacies and mind bogglers suitable for those who like to spend time on their own coping with challenges, and for interweaving in the mathematics classroom for raising students' interest. It covers plethora of topics such as a proof that all obtuse angles are right ones and that all men are bald, a second thought about the truth behind the sum of the angles in a triangle is 180, and behind the infinitude of prime numbers, algebraic demonstration that 2 is greater than 3 and that 0ne equals zero, and many more. How come? Where is the flaw? – seeking answers to these queries bring about sharpening concept understanding and adds to the surprise embedded in doing mathematics. Each task is about 1-2 pages long and is accompanied by explanations and sometimes historical notes as well.
