Symbol; Properties. which are a superset of the natural numbers (i.e. There are several other number classifications as well. Natural numbersare those used to count the elements of a set and to perform elementary calculation operations. For z=r⋅e iθ, the complex logarithmic function: Log(z) = ln(r) + iθ , r >0. If a number is a whole number, for instance, it must also be an Rational numbers; Regarding its origins, Pythagoras, the ancient Greek mathematician proclaimed that all numbers were rational. 1, 2, 3, 4, and so on. ∵ negative numbers are less than positive numbers ∴ If we move on number line from right to left we are getting smaller numbers.
