## Do numbers exist in the real world?

Certainly numbers do not have a tangible existence in the world. They exist in our collective consciousness. And yet they are not arbitrary products of our imaginations in the way that fictional characters are.

## Where can you find real numbers in the real world?

Most numbers that we work with every day are real numbers. These include all of the money that’s in your wallet, the statistics you see in sports, or the measurements we see in cookbooks. All of these numbers can be represented as a fraction (whether we like it or not).

## What is a real world number?

Real numbers include rational numbers like positive and negative integers, fractions, and irrational numbers. In other words, any number that we can think of, except complex numbers, is a real number.

## Whats a number that doesn’t exist?

Perhaps a true zero — meaning absolute nothingness — may have existed in the time before the Big Bang. But we can never know. Nevertheless, zero doesn’t have to exist to be useful. In fact, we can use the concept of zero to derive all the other numbers in the universe.

## Are numbers real philosophy?

Numbers, if they exist, are generally what philosophers call “abstract objects”, and those who maintain that such things exist claim that they exist outside of space and time.

## Why are real numbers important in our world?

Real numbers are all the numbers on the number line, and there are infinitely many of them. Their types and categories are important because they can give you more information about the problem you are looking at.

## Is 0 a real number Yes or no?

The number 0 may or may not be considered a natural number, but it is an integer, and hence a rational number and a real number (as well as an algebraic number and a complex number). The number 0 is neither positive nor negative, and is usually displayed as the central number in a number line.

## Is infinity a real number?

Infinity is a “real” and useful concept. However, infinity is not a member of the mathematically defined set of “real numbers” and, therefore, it is not a number on the real number line.

## Are numbers physical things?

Numbers aren’t made of any mass either — there are no atoms to break down into. As we go through all these questions, we see that numbers don’t follow any of the rules we laid out for physical objects, but they still exist. Thus, physicalism is false.

## Do mathematical objects exist?

Mathematical objects exist outside of concrete time, but they exist inside of mathematical time. So it makes sense to say that a tricle changes its shape with the flow of mathematical time, and that it has three straight edges at some mathematical times, but none at other mathematical times, in the abstract world.

## Are numbers real Plato?

Platonism about mathematics (or mathematical platonism) is the metaphysical view that there are abstract mathematical objects whose existence is independent of us and our language, thought, and practices. Just as electrons and planets exist independently of us, so do numbers and sets.

## Why real numbers are not real?

The absurdity of this conclusion is evidence that real numbers don’t exist because the infinite doesn’t exist and almost every real number requires an infinite number of digits. Real numbers of infinite precision do not occur in reality. In the real world, if you say a voltmeter reads pi volts, you mean 3.14159 volts.

## Do numbers exist independently of humans?

In this view, numbers and circles and so on do exist, but they do not exist independently of people; instead, they are concrete mental objects—in particular, ideas in people’s heads.

## What did Einstein say about numbers?

Albert Einstein once wrote on a blackboard: “Not everything that counts can be counted, and not everything that can be counted counts.”

## HOW DID numbers come to exist?

Numbers, and counting, began about 4,000 BC in Sumeria, one of the earliest civilizations. With so many people, livestock, crops and artisan goods located in the same place, cities needed a way to organize and keep track of it all, as it was used up, added to or traded.

To put it more bluntly, mathematics exists independent of humans — that it was here before we evolved and will continue on long after we’re extinct. The opposing argument, therefore, is that math is a man-made tool — an abstraction free of time and space that merely corresponds with the universe.

## Who invented real numbers?

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

## Who invented 0?

mathematician Brahmagupta

Zero as a symbol and a value
About 650 AD the mathematician Brahmagupta, amongst others, used small dots under numbers to represent a zero.

## Who invented infinity?

infinity, the concept of something that is unlimited, endless, without bound. The common symbol for infinity, ∞, was invented by the English mathematician John Wallis in 1655.

## Who created math?

Archimedes is known as the Father of Mathematics. Mathematics is one of the ancient sciences developed in time immemorial. A major topic of discussion regarding this particular field of science is about who is the father of mathematics.
