A number is real simply because it isn't imaginary; that is, real numbers can never be factored in such a way that one of their factors is an even-root of a negative number or "i" (unless you include enough of those i's so they will cancel each other out). Another way to know that a number is real is to determine whether it's rational or irrational. Rational numbers can be expressed as ratios of integers. For example, -2 is rational because -2 = -2/1 = -4/2 and so forth. Irrational Numbers are usually universally recognized (such as pi and e) or they look like decimal numbers whose digits follow no particular pattern and are infinite in number, such as .0856239... If a number is neither rational nor irrational, it isn't real.

What number is2?
2 is 2, by definition. If you mean "what are it's properties?" it is prime, an integer, a real number and rational.
How is a real number defined?
A real number is any continuous quantity which can be represented as a point on a one-dimensional line. Real numbers are used for measuring properties of objects and phenomena in the natural and social world.
What is the number of properties to rent in Enfield?
As of my last update, I don't have real-time data to provide the current number of rental properties in Enfield. The availability of rental properties can fluctuate frequently due to market conditions. For the most accurate and up-to-date information, I recommend checking local real estate websites or rental platforms.
How are operations and properties of real numbers related to polynomials?
Operations and properties of real numbers, such as addition, subtraction, multiplication, and division, directly apply to polynomials since they are composed of real number coefficients and variables raised to non-negative integer powers. Polynomials can be manipulated using these operations, allowing for the application of properties like the distributive property, the commutative property, and the associative property. Additionally, the behavior of polynomials, including their roots and behavior at infinity, is fundamentally linked to the properties of real numbers. Thus, understanding real number operations is essential for working with and analyzing polynomials.

Properties of real number?
Real numbers have the two basic properties of being an ordered field, and having the least upper bound property. The first says that real numbers comprise a field, with addition and multiplication as well as division by nonzero numbers, which can be totally ordered on a number line in a way compatible with addition and multiplication. The second says that if a nonempty set of real numbers has an upper bound, then it has a least upper bound. These two together define the real numbers completely, and allow its other properties to be deduced.

Order properties of real numbers?
The standard properties of equality involving real numbers are:Reflexive property: For each real number a,a = aSymmetric property: For each real number a, for each real number b,if a = b, then b = aTransitive property: For each real number a, for each real number b, for each real number c,if a = b and b = c, then a = cThe operation of addition and multiplication are of particular importance. Also, the properties concerning these operations are important. They are:Closure property of addition: For every real number a, for every real number b,a + b is a real number.Closure property of multiplication: For every real number a, for every real number b,ab is a real number.Commutative property of addition:For every real number a, for every real number b,a + b = b + aCommutative property of multiplication:For every real number a, for every real number b,ab = baAssociative property of addition: For every real number a, for every real number b, for every real number c,(a + b) + c = a + (b + c)Associative property of multiplication: For every real number a, for every real number b, for every real number c,(ab)c = a(bc)Identity property of addition: For every real number a,a + 0 = 0 + a = aIdentity property of multiplication: For every real number a,a x 1 = 1 x a = aInverse property of addition: For every real number a, there is a real number -a such thata + -a = -a + a = 0Inverse property of multiplication: For every real number a, a ≠ 0, there is a real number a^-1 such thata x a^-1 = a^-1 x a = 1Distributive property: For every real number a, for every real number b, for every real number c,a(b + c) = ab + bcThe operation of subtraction and division are also important, but they are less important than addition and multiplication.Definitions for the operation of subtraction and division:For every real number a, for every real number b, for every real number c,a - b = c if and only if b + c = aFor every real number a, for every real number b, for every real number c,a ÷ b = c if and only if c is the unique real number such that bc = aThe definition of subtraction eliminates division by 0.For example, 2 ÷ 0 is undefined, also 0 ÷ 0 is undefined, but 0 ÷ 2 = 0It is possible to perform subtraction first converting a subtraction statement to an additionstatement:For every real number a, for every real number b,a - b = a + (-b)In similar way, every division statement can be converted to a multiplication statement:a ÷ b = a x b^-1.
