I calculate it.
I specify its value mathematically.
I clearly and definitely identify its numerical amount through mathematics.
I unambiguously establish its quantity expressed as a number, without doubt, by means of the abschract science of number, quantity and space.
I show its amount represented as an arithmetic value expressed by a symbol, representing a particular quantity and used in counting and making calculations, to be certain, in a manner not open to more than one interpretation, in the absence of uncertainty, by using the intellectual activity encompassing the systematic study of arithmetical values, expressed by words, symbols or figures, representing particular quantities and used in counting and making calculations, values that may be expressed in numbers, and the dimensions of height, depth and width within which all things exist and move.
