Nadia distinctively felt the oral questions could be more challenging than the essay ones. She raised her hand as she cleared her throat. "Identity numbers Zero and One are called like that because in certain operations the numbers gives out as result the same number used as second in the operation. For example, sums by zero equals the other number and mutiplication and divition by one gives out the second number as well. This means that as identity numbers, the two numbers has properties that can be used to reveal the identity and hence nature of objects, spells, etc. and as well they work to help reveal hidden magic."

Nadia took a deep breath, she was not done. "Zero represents nothingness to which everything returns since everything can be reduced to zero; this are the bases of the Zeroth Law. Also represents change which happens because and with aid of zero, all other numbers as suceptible to change. One represents unity and identity, for it reveals the identity of other numbers. It also stands for the indentity of a particular that stands in relation to everything else, to 'a whole', which means one is part of the identity of all numbers." She finished dropping her hand and stopped to get some breath.
