No, they are quite real. It is just that in some situations it makes sense to use negative numbers, in others not.

What are examples of real numbers?
1,2,3,4,5,6,1/2, 3/4 these are all real. the square root of negative is an unreal number.
Are unreal numbers undefined?
Yes.For example, any number divided by 0 is unreal. There is no defined representation of (i.e.) 12/0.
What does a negative number plus a negative number equal?
A negative plus a negative still gives a negative answer.
What does a negative number multiplied by a negative number equal to?
A positive number. Positive Number x Positive Number = Positive Number Positive Number x Negative Number = Negative Number Negative Number x Negative Number = Positive Number
Does a negative number minus a negative number equal a positive or negative number?
negative.

What is an unreal number?
Imaginary and complex numbers are an extension of the Real Number system. They are not called unreal. An imaginary number is a non-existent number, like the square root of a negative number. For example, the square root of -4 is 2i (i stands for imaginary). There are also complex numbers, which are defined as the sum of a real number and an imaginary number (e.g. 4 + 3i). An imaginary number does not exist, but can nevertheless be useful in certain applications. An imaginary number is any number that is the product of a real number and the square root of negative one (-1). The square root of -1 is the "unit" of the set of imaginary numbers, and is referred to as "i". As you know, negative numbers cannot have square roots, and so the square root of any negative number is "imaginary". There are also "complex numbers", which are the sum of a real number and an imaginary number. For example 3 + 2i.
What is 1.99 79.99?
It is a number in a unreal way to write it.
Why is square root of the number -9 not a real number?
For the same reason that the square root of ANY negative number is not a real number.Real numbers are positive, negative, or zero. * The square of a positive number is a positive number. * The square of a negative number is a positive number. * The square of zero is zero. In other words, in no case will you get a REAL number whose square is a negative number. The square roots of negative numbers are said to be "imaginary" - a name given for historical reasons. They are just as "real" or "unreal" as the so-called real numbers, but the point is that they are a different kind of numbers.
Are unreal numbers undefined?
Yes.For example, any number divided by 0 is unreal. There is no defined representation of (i.e.) 12/0.
The real fourth roots of -16?
there are no real answers to an even root (2,4,6,8) of any negative number. the innovation of i allows you to find the unreal answers. i= the fourth root of positive 16 is 2. so, the roots of -16 are positive and negative 2i. post script: you cannot have a real even root of a negative because a negative multiplied by a negative turns into a positive.
