You cannot. The diagonal of a unit square cannot be represented by a rational number. However, because rational numbers are infinitely dense, you can get as close to an irrational number as you like even if you cannot get to it. If this approximation is adequate than you are able to represent the real world using rational numbers.
An overdrawn balance on your bank account is a negative number !
In the real world you can use the order of rational numbers. This is used a lot in math.
Any time that you want to count or share anything.
False
That refers to a system to represent numbers. For example, the decimal system we use in most of the world.
Loss or negative growth, mostly in economic matters temperature
The number problem is a problem of problem of the whole world with numbers ... lol xD...
An infinite amount because there are an infinite amount of numbers that you can keep adding to.
It was invented in prehistoric times and has evolved as our understanding and needs developed.From natural (counting) numbers to the set of integers, to rational numbers (fractions) to real numbers (incorporate irrational numbers), to complex numbers and then quaternions. The last of these, which even many mathematicians will not have come across in their work, were formally introduced to the world of mathematics by Hamilton in 1843.
There are very many uses for irrational numbers. A square, whose sides are a rational number, will have a diagonal of irrational length. The diagonals of most rectangles, with rational sides, will be irrational. The circumference and area of a circle (or ellipse) is related to pi, an irrational number. In the same way that pi is central to geometry, another irrational number, e, is fundamental to advanced calculus.
They were attempting to represent the world and all its beauty
The globe represent the world; or in this case, Earth.
