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.

Three billion, five hundred fifty five million, three hundred eight thousand, seven hundred twenty five.
In fraction notation 265/125 = 2 3/25. 3/25 in decimal notation is 0.12. Therefore the answer is 2.12 in fraction notation.
a number that cant be written on a number line. (ex. √-1) (the check is a square root sign)
If you use the number 5 for five times in any mathematical problem how do you equal 3?
5 - 5/5 - 5/5 = 3
In the game of chess is there an infinite number of moves or a finite number of moves?
There's an infinite number of moves. Although there's a limited number of moves a play can make at the start of the game (There are only 10 possible choices for each player's first move) - each move generates numerous subsequent possibilities.
How do you define 'number' in mathematics?
A number is a word used to indicate some whole or sum and the parts or individuals therein. Numbers are mostly represented in mathematics by symbols called numerals. Numbers are employed not just in mathematics but in a wide variety of other fields. They are used for counting, ordering, calculating, measuring, and labeling.
If: 11x+13y = 17
Then: 11/17x +13/17y = 1 by dividing all terms by 17
So: 11/17*17/22+13/17*17/26 = 1 because 1/2+1/2 = 1
Therefore: x = 17/22 and y = 17/26
Check: 11(17/22) + 13(17/26) = 17
Check: 11(17/22) times 13(17/26) = 72.25
Do all event number have 2 as a factor?

If you are looking for the next whole number, it would be 900991.
What two numbers are closest to the square root of 7?
The answer is sqrt(7) since there are infinitely many numbers between sqrt(7) and any other number. So if x is a number laying claim to being the closest, then there are infinitely many numbers between x and sqrt(7) and so each one of them is closer to sqrt(7) totally invalidating x's claim of being closest.
The closest integers, are -3 and +3.
