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.

How is pi a non rational number?
I'm not sure whether u r asking what it means that pi is not rational (irrational is the word 4 that) or how 2 prove it. The 1st of those is much easier 2 answer. It means that there r no 2 integers (whole numbers) that u can divide, 1 by the other, 2 get a fraction that is exactly equal 2 pi.
It turns out that pi is not only irrational, but transcendental, which means it is not the root of any polynomial equation with rational coefficients. While the ancient Greeks knew about pi, and its approximate value, the irrationality of it was not proved until 1761, and its transcendence until 1882
What is the use of finding number of tiles in daily life?
Well just say your wife/husband wants you to tile the bathroom. Instead of buying a random amount of tiles you can simply measure the area you want tiled to figure out the exact number of tiles needed. This is a pretty literal real life application though. Basically the tiles per certain area exercise also has the effect of teaching one how to deduce how many units [the tiles] will fit into a certain space [the area] this has all sorts of real world applications to do with problem solving if you really think about it and even though when I was in school I found these kinds of exercises pointless I often use the things I learnt in real life now :D
523 is a prime number. Its only positive integer factors are itself and 1.
What is the product of a number n 1 and the number n plus 1 is always equal?
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "equals".
There is no symbol between the first n and 1.
Assuming the question is about (n-1)*(n+1) , this is identically equal to n2-1

Why do you need whole numbers?
Whole numbers are easier to calculate with. For example if a dollar was not 100
cents but 122.5 cents, it will be really hard to work out change

Put simply, nothing we experience in our direct day to day life is in fractions until we do something to make it so - an orange is a whole fruit until we cut it into halves or quarters....
