# Who discovered complex numbers in mathematics?

That's difficult to say. Rafael Bombelli defined an imaginary
number in 1572, but Rene Descartes actually gave the term
*imaginary*. Nobody seemed to have much use for them until the
work of Euler and Gauss in the 1700's and 1800's. This information
I got from the Wikipedia article on Imaginary Numbers.

### What are the compex roots in mathematics?

The complex roots of an equation is any solution to that equation which cannot be expressed in terms of real numbers. For example, the equation 0 = x² + 5 does not have any solution in real numbers. But in complex numbers, it has solutions. Read More

### Who is the inventor of prime numbers?

Mathematics, including prime numbers, is discovered, not invented. Systems and methods we use are invented, but concepts of relationships between objects governed by logic, such as the prime numbers are discovered and named. As such, a more appropriate question might be "Who discovered prime numbers?" Many have discovered prime numbers; the first is unknown to mankind. Read More

### How do you find the square root of negative numbers?

For most school mathematics, negative numbers do not have square roots. This is because a negative number multiplied by itself is a negative times a negative and so is positive. When (if) you study advanced mathematics, you will learn that there is a solution and this falls within the realms of complex mathematics and imaginary numbers. Read More

### What are the roots of complex numbers in mathematics?

See the answer to the related question: 'How do you solve the power of an imaginary number?' (Link below) Read More

### What is the product of a binomial and its conjugate pair called as in vocabulary?

The answer depends on the level of mathematics. With complex numbers, it is the squared magnitude of the binomial. Read More

### Why are some numbers skipped in vitamin B complex?

Some numbers are skipped in the vitamin B complex due to the sequence in which they are constructed and the order in which they were discovered. There are a total of 8 B complex vitamins ranging from B-1 to B-12. Read More

### Does root negative nine exist in math?

It depends what level of mathematics you are talking about. There is no real number whose square is -9. Once we introduce complex numbers, there are two possibilities, 3i and -3i. Whether you allow complex numbers depends on what you are trying to do. They are unlikely to show up in mathematics before college level, but they are useful in engineering and other areas.

### What is the difference between arithmetic and algebra?

Arithmetic: The mathematics of integers, rational numbers, real numbers, or complex numbers under addition, subtraction, multiplication, and division. Algebra: A branch of mathematics in which symbols, usually letters of the alphabet, represent numbers or members of a specified set and are used to represent quantities and to express general relationships that hold for all members of the set.

### Why is i used for electrical current?

It is mostly convention. However this produces conflicts with the conventional mathematics usage of i as the square root of -1 in complex numbers, so in electronics the convention is to use j as the square root of -1 instead when working with complex numbers in the analysis of AC circuits. Read More

### Why was complex numbers discovered?

They were discovered when Cardano solved the third degree equation. In the formulas that arose to solve the third degree equation, Cardano needed to take the square root of negative numbers and add them up in a certain way. The strange thing that happened was that the formulas used these complex numbers, even if the solutions to the equation where all real. This baffled the mathematicians of the time, because how could these strange numbers… Read More

### What is complex math?

### Was mathematics discovered or created?

Both. Some mammals and birds, and possibly other creatures, have a basic sense of arithmetic such as the conservation of numbers. To that extent mathematics is discovered. Many concepts of mathematics, even fairly advanced ones such as the Fibonacci sequence, do exist in nature but they had to be noticed and then identified. Sometimes, the concepts had to be made ideal. To illustrate what I mean: there can be no line in nature since a… Read More

### What are examples of infinity sets?

Many infinite sets appear in mathematics: the set of counting numbers; the set of integers; the set of rational numbers; the set of irrational numbers; the set of real numbers; the set of complex numbers. Also, certain subsets of these, such as the set of square numbers, the set of prime numbers, and others. Read More

### What is the relation of complex numbers to real numbers?

Complex numbers are a proper superset of real numbers. That is to say, real numbers are a proper subset of complex numbers. Read More

### Name the set or sets of numbers to which the real number belongs?

Say if the number is a whole,integer,rational, or irrational. For example: -3.5 is irrational. But 2 is whole, integer, and rational. * * * * * The above is absolute rubbish. -3.5 is rational (-7/2), not irrational. Also, it mentions the subsets of real numbers, whereas the question is about what the real numbers are a subsets of - the supersets of real numbers. Actually, the set of real numbers is probably the largest set… Read More

### Could anyone list numbers not in the set of complex numbers?

No. Complex numbers is the highest set of numbers you can go, and there are no sets outside of complex numbers. Read More

### Are all numbers real number?

The real numbers are made up of: - natural numbers - zero - negative integers - fractions (rational numbers) - algebraic irrationals - like the square root of 2 - transcendental numbers - like pi It's likely that natural numbers - counting numbers - were known before recorded history. The more unusual kinds of real numbers were gradually understood as mathematics developed. You can't say that any particular person "discovered" the real numbers. Read More

Think of the complex numbers as points on a coordinate system. Instead of the usual x-axis you have the real numbers, instead of the y-axis, you have the imaginary numbers. The real numbers are on the horizontal axis. The imaginary numbers are on the vertical axis. The complex numbers are any number on the plane. The non-real complex are, of course, any complex numbers that are not on the real number axis - not on… Read More

### What might be classed as a complex relationship?

The validity of this answer depends on whether or not is has been classified correctly! It has been classified to complex numbers, a rather esoteric part of mathematics and if you were hoping for an explanation in terms of personal relationships, I apologise. The classification was carried out by a bot which is usually pretty accurate but when it gets things wrong ... oh boy, does it get it wrong! That really drives me up… Read More
