Numbers
Numbers are our way to quantify, label, and organize the world around us in a logical manner. However, the systems used to obtain this goal differ geographically, historically, and by relative utility. All questions pertaining to numbers, including historic labeling systems, bases of numerical systems, constants, and the various ways they're grouped together, should be placed into this category.

Notwithstanding todays modern configuration of Roman numerals inasmuch that there is substancial evidence to qualify the fact that the ancient Romans would have worked out the equivalent of 1 to 2000 on an abacus counting device as follows:-
1 to 9: I, II, III, IIII, V, VI, VII, VIII and VIIII
10 to 90: X, XX, XXX, XXXX, L, LX, LXX, LXXX and LXXXX
100 to 900: C, CC, CCC, CCCC, D, DC, DCC, DCCC and DCCCC
1000 and 2000: M and MM
To select any numerals simply write them out in descending order as in the examples: 1776 = MDCCLXXVI and 1666 = MDCLXVI
Note that sometimes it's possible to abridge numerals thus using less numerals but of equal value as the following examples show:-
4 = IIII => IV (5-1)
9 = VIIII => IX (10-1)
19 = XVIIII => IXX (20-1)
49 = XXXXVIIII => IL (50-1)
1999 = MDCCCCLXXXXVIIII => IMM (2000-1)
The way we write out Roman numerals today is because the real rules governing the Roman numeral system were changed in the Middle Ages presumably to make Roman numerals more compatible with Hindu-Arabic numerals that were being intoduced into Western Europe at the time.
QED by David Gambell
Why the natural numbers are called so?
They are the numbers that are used for counting objects. They form the basis of the number system. Even so, why "natural", and not primary (like in colours) I don't know.
Yes, 1460 is an even number, as it can be divided by 2 without a remainder.
k-2 is an expression, not an equation nor an inequality. It is, therefore, not something that can be "solved". Also, since k is not known, it does not have any answer.
