Can you find a real-world situation that numbers don't describe? From the numbers on your alarm clock to the numbers on your house, to the bus you ride to work, to the numbers on the phone as you order takeout, to the prices at the grocery store, to your bar tab, it's all numbers.
define or describe each set of real numbers?
well naruto is not real in the realworld so of course ....no and never
Any situation numbers are used.
A coordinate graph is a graph of pairs of numbers that represent real-life situations.
In the real world you can use the order of rational numbers. This is used a lot in math.
This question is kind of vague. Many of your everyday situations use the rational numbers (fractions and integers), which are a subset of real numbers. If you do anything with angles (like surveying, or navigation) then irrational (which are still real) come into play. There are situations when it's necessary to consider complex (a combination of real and imaginary) numbers. When dealing with waves or periodic motion, imaginary numbers become an important thing to consider.
i dont know or care
There are many situations where integers are simply not enough. However, "real numbers" are mainly of theoretical importance; for most practical situations, numbers that have a limited number of decimals work quite well.
natural numbers
scatter plots, you see show this information.
The set of real numbers is the union of the set of rational and irrational numbers. But there are so many other ways to describe it. Real numbers can be constructed as Dedekind cuts of rational numbers. The set of real numbers can also be viewed as the set of equivalence classes of Cauchy sequences of rational numbers Some people like the definition, that the real numbers are all the numbers which can be expressed as decimals.
