Don’t be a Mathematician, Be a Mathemagician
We all like to impress others. It is a natural tendency. In this page I will share certain maths tricks with you (which I learnt from Benjamin and Shermer), which you can use to impress your family members, friends, colleagues or acquaintances. They will be swept off their feet when you do this. So get ready to be in the limelight. Become a mathemagician.
