The real numbers together with the imaginary numbers form a sort of vector. What these complex numbers (complex means the combination of real and imaginary numbers) represent depends on the specific situation. Just as there are situations where it doesn't make sense to use negative numbers, or fractional numbers, in many common situations it doesn't make sense to use complex numbers. In an electrical circuit (specifically, AC), the real numbers might represent resistance, while the imaginary number represent reactance - and voltages and currents are also represented by complex numbers, with the angle of the complex number representing how much one quantity is ahead or behind another quantity (the "phase angle"). In quantum mechanics, the complex numbers might not represent anything (perhaps they don't, I am not sure...), but they are useful for calculations.
What else can I help you with?
Are decimals imaginary number?
No, decimals are not imaginary numbers. Decimals are a way to represent real numbers, which can include both rational numbers (like 0.5 or 3.75) and irrational numbers (like π). Imaginary numbers, on the other hand, are defined as multiples of the imaginary unit (i), where (i^2 = -1), and they are used to extend the concept of numbers beyond the real number line.
Can a complex number be imaginary?
Yes, imaginary numbers are a subset of complex numbers.
What is the difference between imaginary numbers and complex numbers?
No difference. The set of complex numbers includes the set of imaginary numbers.
Is the imaginary unit 8i irrational?
No, it is imaginary. Irrational numbers are a subset of real numbers Real numbers and imaginary numbers are sets without any overlap.
What is subset of imaginary numbers?
A subset of imaginary numbers consists of numbers that can be expressed in the form (bi), where (b) is a real number and (i) is the imaginary unit, defined as (i = \sqrt{-1}). This subset includes numbers like (2i), (-3.5i), and (0.1i). Imaginary numbers can be thought of as a special case of complex numbers, which have both a real part and an imaginary part.

Are imaginary numbers irrational numbers?
No. Irrational numbers are real numbers, therefore it is not imaginary.
Who was the first person to use the symbol for imaginary numbers?
The first person to use the symbol for imaginary numbers, specifically the letter "i," was the mathematician Leonhard Euler in the 18th century. He introduced this notation in his work to represent the square root of -1, which helped formalize the concept of imaginary numbers. Euler's use of "i" has since become standard in mathematics.
Can a complex number be imaginary?
Yes, imaginary numbers are a subset of complex numbers.
Which of these sets of numbers is not a subset of the real numbers irrational integer rational and imaginary?
Imaginary numbers are not a subset of the real numbers; imaginary means not real.
What is the difference between imaginary numbers and complex numbers?
No difference. The set of complex numbers includes the set of imaginary numbers.
Is the imaginary unit 8i irrational?
No, it is imaginary. Irrational numbers are a subset of real numbers Real numbers and imaginary numbers are sets without any overlap.

What are imagery numbers?
imaginary numbers are numbers that are a negative square root, which is not possoble therefor it is called and imaginary number. ex the square root of -24 is an imaginary number
Which number belongs to the set of imaginary numbers 2?
2 does belong to the set of imaginary numbers. Any real number is also imaginary. Imaginary numbers are the set of all numbers that can be expressed as a +b*i where "i" is the square root of negative one and "a" and "b" are both real numbers.
Is the set of imaginary numbers closed under subtraction?
Yes, the set of imaginary numbers is closed under subtraction. This means that if you take any two imaginary numbers, their difference will also be an imaginary number. For example, subtracting ( bi ) from ( ai ) (where ( a ) and ( b ) are real numbers) results in ( (a - b)i ), which remains an imaginary number. Therefore, the set of imaginary numbers is closed under this operation.
What numbers are not real?
Imaginary numbers are not real numbers.
