Calcadabra

Calcadabra: math tricks, money spells and a wizard named Cal

Cal is an old wizard who thinks numbers are the most useful magic there is. His cat Pi thinks numbers are for knocking off the desk.

On this channel you'll find:

Cal's Quick Spells: mental-math tricks you can use at the checkout, the restaurant or the bank, in under 30 seconds.
Cal Explains: Cal walks you through a real calculator on screen. Compound interest, credit card payoff, the rule of 72 and more.
Cal & Pi: life in the study. Mostly Pi breaking things.
