Any situation numbers are used.
Practically every application of numbers for ordinary every day real life is a real number (versus imaginary or complex numbers).Counting numbers (1,2,3,...) are natural numbers. If you use zero, then you have whole numbers. Negative numbers (used in temperature, altitude, banking, and others). Now you have the integers. Speaking of banking, with dollars and cents, you now have rational numbers (pennies are 1/100 cent). Other fractions (rational) are in use as well.Irrational numbers can be used to calculate materials needed (say you want as square with 10 square feet area, to find the perimeter: one side is square root of 10 (irrational number) then multiply by 4, to find the amount needed for all four sides. A real person would round this to whatever precision is convenient. Another commonly used irrational number is pi (rounded off to 3.1416 or so) which is used to find the area and circumference of circles.
In the complex field, every number is a square so there are no numbers that are not squares. If the domain is reduced to that of real numbers, any negative number is not a square. However, the term "square numbers" (not number's!) is often used to refer to perfect square numbers. These are numbers that are squares of integers. Therefore the squares of fractions or irrational numbers are non-squares.
numbers are used in every day life such as how old are you? whats 2+2? <forget that> if your talkin about real number as in |-26| = 26 then yeah forget it. I think that real numbers would be used in things like how far are you away from something for example you wouldn't need to know if you are - amount away or + just that you are a certain distance.

Real numbers are used in real life in like the discount prices of a sale or when a teacher grades your paper.... there are lots more... :) ADDED: Put simply, the Real Numbers are those in which we count or measure real things: objects, people, money, distances, weights, etc..

Signed numbers are used for:TemperatureMoney, Accounting, or EconomyMath Problems

natural numbers are used in real life for counting, adding, subtracting and even for calculting money purposes

i dont know or care
An imaginary number i is defined as the square root of -1, so if you have something like the square root of -2, the answer would be i root 2, and that would be considered an irrational non-real number.* * * * *Not quite. The fact that irrational coefficients can be used, in conjunction with i to create complex numbers (or parts of complex numbers) does not alter the fact that all irrational numbers are real numbers.
