"Mathematics is logical systems formulising relationships of variable(s) with other variable(s) quantitatively &/or qualitatively as science language." (Sinan Ibaguner)
I tried to devise my best description as shortly & clearly !
The statement ends with a question mark, but it is not even a question. Assuming it is a question, the question is vague. What exactly is the question? Please clarify.
"Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics with the major subdisciplines of number theory,[1] algebra,[2] geometry,[1] and analysis,[3][4] respectively. There is no general consensus among mathematicians about a common definition for their academic discipline."

As stated in wikipedia there is no common definition at all. Since I did not find any sufficiently satisfactory clear and short definition of maths, therefore I devised my own original definition which seems to be the best until now, at least for me ! I wait from readers, to criticise me about my own definition of maths...
