## Who invented real numbers in mathematics?

Mathematician Richard Dedekind

Mathematician Richard Dedekind asked these questions 159 years ago at ETH Zurich, and became the first person to define real numbers.

## Who was the first real mathematician?

Thales of Miletus

One of the earliest known mathematicians were Thales of Miletus (c. 624–c. 546 BC); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed.

**Who created numbers?**

The Babylonians got their number system from the Sumerians, the first people in the world to develop a counting system. Developed 4,000 to 5,000 years ago, the Sumerian system was positional — the value of a symbol depended on its position relative to other symbols.

### Who invented imaginary numbers?

Although the Greek mathematician and engineer Hero of Alexandria is noted as the first to have conceived imaginary numbers, it was Rafael Bombelli who first set down the rules for multiplication of complex numbers in 1572. The concept had appeared in print earlier, such as in work by Gerolamo Cardano.

### Who is the father of complex number?

The first indications that complex numbers might prove useful emerged in the 16th century from the solution of certain algebraic equations by the Italian mathematicians Girolamo Cardano and Raphael Bombelli.

**Who was the first person to believe in math?**

The independent reality of math has some ancient advocates. The Pythagoreans of 5th Century Greece believed numbers were both living entities and universal principles. They called the number one, “the monad,” the generator of all other numbers and source of all creation.

#### Who was the first person to discover real numbers?

The kinds of magnitudes Eudoxus (and Euclid after him) were primarily concerned about were line segments, plane figures, angles, and solid figures. We cannot credit any one person with this invention ∗, because “the real numbers” developed over a few thousand years. A brief history is found, as usual, on Wikipedia: real number.

#### Can you argue that mathematics is invented by humans?

In that sense you can argue that mathematics is invented by humans. Any mathematical object exists only in our mind and doesn’t as such have an existence. ” Platonists “, on the other hand, argue that any mathematical object exists and we can only “see” them through our mind.

**When did mathematicians begin to develop different types of numbers?**

During the 19th century, mathematicians began to develop many different abstractions which share certain properties of numbers and may be seen as extending the concept. Among the first were the hypercomplex numbers, which consist of various extensions or modifications of the complex number system.
