What is the most powerful number in the world? A million? One billion? A googol? But no, it's zero! There is nothing there! It's not magic ... it's mathematical! The pedagogical side: This segment deals with the enormity and the quantity of high numbers. We present the location reserved for the zero for high numbers such as one million, one billion and one trillion. We also introduce the notions of the position value and the elevation to a power of ten with pearls.
