The concept of negative numbers was first developed by Indian mathematician Brahmagupta in 628 CE. His book, Brahma Sphuta Siddhanta, is one of the oldest known mathematical works and details the mathematical operations, including the law of integers and the solution of linear and quadratic equations.
In his work he describes negative numbers, zero and positive numbers as being “separate creatures. ” He also gave the algorithm for calculating the difference between two negative numbers and multiplied positive and negative numbers.
Negative numbers were then adopted and developed by Arab mathematicians and eventually spread to Europe and other parts of the world.

How were negative numbers invented?
Negative numbers have been around for centuries, but the concept of negative numbers wasn’t formally accepted until the 17th century. Before then, it was believed that only positive numbers existed in nature.
The invention of negative numbers can be attributed to two mathematicians, René Descartes and Pierre de Fermat.
In 1620, Descartes published a book titled “La Geometrie” (The Geometry) and introduced the concept of negative numbers as signed numbers: numbers that could represent both positive and negative values.
Descartes argued that because you can subtract a greater number from a lesser number, the result could be signed as either “minus” or “plus” depending on its value. For example, if you subtract five from two, the result is negative three.
In 1637, mathematician Pierre de Fermat provided more evidence for this idea. Fermat used an algebraic equation to prove that a negative number could be used to solve problems. He also introduced the concept of negative exponents, which showed that certain equations could only be solved by introducing negative numbers.
So technically, negative numbers can be attributed to the combined works of both Descartes and Fermat. Their theories on signed numbers and negative exponents paved the way for future mathematicians to explore and define the appropriate uses of negative numbers.
Who was the first person to invent the negative?
Joseph Nicéphore Niépce is widely credited as the inventor of the first photographic negative in 1824. Niépce, who lived in France, created his negative by coating a pewter plate with a thin layer of bitumen of Judea, which was a fluid chemical that hardened upon exposure to light.
Niépce then exposed the plate to sunlight, which hardened the parts that were exposed and thus forming a negative image. Niépce then put the plate in a solutioon that etched the exposed portions of the plate away, leaving only an image of the shadows.
Up until this point, cameras used a direct positive processing technique, where the picture was taken directly onto a light-sensitive material, such as paper. Niépce’s invention was a revolutionary moment in photography as it opened up a range of image editing possibilities.
Is negative 0 possible?
Yes, negative 0 is definitely possible in mathematics. Negative 0 is related to two’s complement and a concept known as signed magnitude representation. This type of representation is a way of interpreting binary, or base 2 number systems.
A binary representation of 0 is normally just a series of all 0s, but with negative 0, a binary representation is all 0s with a single 1 at the highest order of magnitude. In other words, it is a number that is equal in magnitude to the positive 0, but with the opposite sign.
Negative 0 is not really a “real” number, but rather just a representation of a certain number.
For all practical purposes, negative 0 is the same as positive 0. Adding two negative numbers together, for example, will result in a number with a negative 0 sign (like -0). Although, negative 0 is not fully supported across all programming languages and programming platforms.
This means that when programming, it is important to pay attention to the type of number representations.
What came first 0 or negative numbers?
Negative numbers technically came before zero as they were invented by Indian mathematicians as early as the 9th century. According to some historians, Brahmagupta was the first to introduce negative numbers and zero in his book called the Brahma Sphuta Siddhanta.
This was around 628 AD. Although the Indian mathematical sciences had already started studying algebra and arithmetic, Brahmagupta made an unprecedented advancement by understanding negative numbers, and how they could be used.
He is credited with understanding that negative numbers are actually numbers and not just a lack of a quantity as some thought before him. He also understood that when negative numbers are used in calculations, the value can be zero.
Arguably, however, certain Indian mathematicians, such as Pingala and Virahanka, may have already used negative numbers for negative integers and zero for the empty set prior to Brahmagupta. After Brahmagupta’s groundbreaking work, other mathematicians started to build upon his knowledge to further elaborate on the concept.
Why do 2 negative numbers make a positive?
When two negative numbers are multiplied together, the result is a positive number because multiplying a negative number by a negative number is like taking an even number of steps backwards. For example, if you take two steps backwards (which you can think of as -2 steps), you end up in the same place that you started, just like if you multiply -2 by -2, you end up with +4.
So two negative numbers multiplied together always result in a positive number.
How was number system before zero?
Prior to the existence of zero, ancient civilizations used other symbols to indicate an empty place holder or a lack of a certain quantity. The Babylonians and ancient Egyptians used a single diagonal stroke to represent the concept of “nothing”, while the ancient Greeks developed various symbols for zero such as a circle with an empty center, a magnifying glass, or an upside-down horseshoe.
In the Mayan civilization, a shell shape was used instead. In India, the traditional number system was a positional system meaning the value of a unit depended on its location relative to other units, and this is thought to be the first use of zero around 600 B.
C. This form of number system was seen in the Arab world by 8th Century A. D. and passed on to Europe in the 12th Century by Fibonacci and other mathematicians.
When did humans start using negative numbers?
Humans have been using negative numbers for thousands of years. Records from ancient Babylon show that the first recorded use of a negative number was as early as 1800 BCE. The use of negative numbers was used to indicate debts and was documented in the ancient Egyptian Rhind papyrus, which dates to around 1650 BCE.
Another early example of negative numbers comes from the Chinese book “Nine Chapters on the Mathematical Art” which was written by Zhuang Zi around 200 BCE. Here the use of negative numbers was used to calculate the areas of rectangles and triangles.
It wasn’t until the 16th century, when the modern idea of negative numbers was first introduced by German mathematician and philosopher Gottfried Wilhelm von Leibniz. He formalized the concept of negative numbers, giving them negative signs, performing calculations and adding notation to represent them in his publication, “De Sectionibus Conicum”, in 1684.
Since then, the concept of negative numbers has been a cornerstone of mathematics and has been widely used in the fields of engineering, finance, and science.
Does negative infinite exist?
Yes, negative infinity does exist. Generally speaking, infinity can be thought of as a sort of concept or idea rather than an actual physical quantity. Negative infinity is the exact opposite of infinity, representing a seemingly endless negative number.
In mathematics, negative infinity is usually represented with a negative sign followed by an infinity symbol, like this: -∞.
It is important to note that infinity is not a number, but rather a concept. Negative infinity is not a measurable quantity and thus cannot be accurately represented in terms of numerical measurements.
To illustrate this idea, think of a computer, where it would be impossible to measure something that is infinitely small, such as negative infinity.
Negative infinity has a number of uses in fields such as physics and mathematics. In physics, negative infinity can be used to describe the temperature in a vacuum, where the temperature is so low that it reaches an effectively infinite negative value.
In mathematics, negative infinity can help to define certain types of functions, such as the logarithm, and it can also serve as a limit to certain types of equations.
Overall, negative infinity does exist, and it can be used in mathematical and physical calculations in order to simplify problems or equations. However, it is important to remember that negative infinity is a concept and not an actual measurable quantity.
What is the largest negative natural number?
The largest negative natural number is -1. This is because in mathematics, negative numbers are defined as any real number that is less than 0. The largest of these is -1. It is not possible to have a number lower than -1 because it would not represent a real number.
For example, -2 would be a number lower than -1, but it cannot exist because it is not a real number.
How did people come up with negative numbers?
The concept of negative numbers dates back to the ancient Indian scholars, who worked on the Sulba Sutras, a series of mathematical problem-solving texts, during the 8th century BC. The first use of negative numbers, however, dates back to the Chinese Nine Chapters on the Mathematical Art, a mathematical text written during the 2nd century BC.
In the Western world, the concept of negative numbers was first developed by the Babylonian and Greek mathematicians, who used them to solve equations and understand relationships between number quantities.
The Greek mathematician Diophantus of Alexandria was the first to officially use negative numbers, sometime during the 3rd century AD.
It wasn’t until the late 16th century, however, that the Italian mathematician Gerolamo Cardano officially recognized and popularized the use of negative numbers. Cardano believed that negative numbers had a “real physical significance”.
He shared his findings with the world in 1545 – and introduced the modern-day sign for negative numbers.
Cardano’s influence is still evident in the world of mathematics today, as his pioneering breakthrough made it possible for modern mathematicians to build on and expand his work on the subject of negative numbers.
Can there be a negative 0?
No, a negative 0 does not exist. While it might seem like a negative number could be added to 0 in theory, both the positive and negative number systems were created to provide a way to measure a difference between two numbers.
Mathematically, any time a negative number is added to a positive number, the result is a negative number. Therefore, adding a negative number to 0 would not produce a valid result and would not be a valid zero.
What culture used black rods for negatives and red rods for positives?
The Mayan culture used black and red rods to represent mathematical calculations. The rods were known as kakaw and used by ancient Mayans for a variety of mathematical purposes. The black rod represented a negative number, whereas the red rod was used for a positive number.
The Mayans would add the rods together to calculate a number and then used the overall length of the rods to represent the number. The kakaw was used by Mayans to calculate weight, length, size, surface areas and even volume.
The ancient Mayans also used the kakaw to make astronomical calculations. They would track eclipses and the stars with accuracy, by combining the black and red rods to find the exact location of stars and planets.
The ancient Mayans used the black and red rods in different combinations to calculate mathematics problems and make astronomical calculations.
When did China recognize negative?
China recognized negative numbers as early as the 2nd century BC. Around this time, the mathematician Zu Chongzhi wrote the mathematical text, the Nine Chapters on the Mathematical Art, which covers topics such as fractions, prime numbers, and negative numbers.
There is also evidence of Chinese mathematicians using negative numbers prior to this period, but Zu Chongzhi’s text is the first known solidification of these concepts in written form. The Nine Chapters advance the understanding of negative numbers, as mathematicians during his time did not have a complete understanding of the concept.
Who was the first mathematician to use negative numbers?
The use of negative numbers can be traced back as far as around 500 BCE in India, where mathematicians were using such primitive types of arithmetic operations. However, the first formal use of negative numbers was in the 7th century by Indian mathematician Brahmagupta.
He was the first to provide rules and formulas to handle fundamental operations such as addition, subtraction, multiplication and division, applied to both positive and negative numbers.
Brahmagupta also described the first-known algorithm for solving the general quadratic equation, which, with some modifications and simplifications, is still used today. During Brahmagupta’s time and right up until the 17th century, negative numbers were not widely accepted and he received criticism for his development.
However, their practical usage in real-life problems gradually made them accepted as part of the mathematical system.
The 17th century saw a shift in terms of the reception of negative numbers. English mathematician John Wallis published a mathematical textbook in 1685 that set out the rules for adding and subtracting negative numbers in a systematic manner.
By the 18th century, negative numbers were established as a valid and useful part of mathematics, and officially accepted by the mathematical community.
