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.

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.
(positive number) x (positive number) = positive number (positive number)/(positive number) = positive number (positive number) x ( negative number) = negative number (positive number)/( negative number) = negative number (negative number) x (negative number) = positive number (negative number)/(negative number) = positive number
A negative number divided by a negative number is a positive number.
Yes. 81 is a:- Real number - Rational number - Integer - Natural number - Counting number - Square number - Odd number
A negative number divided by a positive number will be a negative number. For example: -20 / 4 = -5 -100 / 2 = -50 Here are the other cases of division by positive or negative numbers. A negative number divided by a negative number would be a positive number. A positive number divided by a positive number would be a positive number. A positive number divided by a negative number would be a negative number.
It is a number in a unreal way to write it.
Yes.For example, any number divided by 0 is unreal. There is no defined representation of (i.e.) 12/0.
