The first mention of negative numbers can be traced to the Chinese in 200 B.C.E. The Chinese used red rods to represent positive numbers, but black rods to represent negative numbers. In the fourth century, the Alexandrian mathematician Diophantus said in his text Arithmetica that the following equation is absurd.

17th and 18th Century. In the early 18th (or very late 17th) century John Wallis was the first European mathematician to give negative numbers meaning.
Who invented negative numbers?
The Indian mathematician Brahmagupta
Do negative numbers exist in real life?
However, people in India and China have been using negative numbers for millennia. Eventually, the Europeans came around, and we use negative numbers everywhere today. Negative numbers might seem mysterious in math problems. For many people, real-world negative numbers make more sense.
Who discovered 0?
The first modern equivalent of numeral zero comes from a Hindu astronomer and mathematician Brahmagupta in 628. His symbol to depict the numeral was a dot underneath a number.
Is 0 an even number?
So what is it – odd, even or neither? For mathematicians the answer is easy: zero is an even number . ... Because any number that can be divided by two to create another whole number is even. Zero passes this test because if you halve zero you get zero.
Is 0 a real number?
Real numbers can be positive or negative, and include the number zero . They are called real numbers because they are not imaginary, which is a different system of numbers.
What is the opposite of 0?
The opposite of zero is negative zero .
Why zero is not positive or negative?
Negative numbers are numbers that are smaller than zero, and positive numbers are numbers that are bigger than zero. Since zero isn’t bigger or smaller than itself (just like you’re not older than yourself, or taller than yourself), zero is neither positive nor negative .
What is not a real number?
what is NOT a Real Number? Imaginary Numbers like √−1 (the square root of minus 1) are not Real Numbers. Infinity is not a Real Number. Mathematicians also play with some special numbers that aren’t Real Numbers.
Is there a negative zero?
Negative zero has the sign bit set to one . One may obtain negative zero as the result of certain computations, for instance as the result of arithmetic underflow on a negative number, or −1.0×0.0 , or simply as −0.0 .
What numbers can be negative?
Negative numbers are symbolized by a minus or a dash (-) sign in front of a number. They are represented on the number line to the left of origin. Negative numbers can be either be whole numbers, fractions or decimals . For instance, – 2, – 3, – 4, – 5, -2/3, -5/7, -3/4, -0.5, -0.7.
Which is the smallest whole number?
The smallest whole number is “ 0 ” (ZERO).
What is a 0 in math?
Zero is the integer denoted 0 that, when used as a counting number, means that no objects are present . It is the only integer (and, in fact, the only real number) that is neither negative nor positive. A number which is not zero is said to be nonzero. A root of a function is also sometimes known as “a zero of .”
Who is the father of mathematics?
Archimedes is considered the father of mathematics because of his notable inventions in mathematics and science. He was in the service of King Hiero II of Syracuse. At that time, he developed many inventions. Archimedes made out a pulley system designed to help the sailors move objects up and down that are weighty.
Who found maths?
Beginning in the 6th century BC with the Pythagoreans, with Greek mathematics the Ancient Greeks began a systematic study of mathematics as a subject in its own right. Around 300 BC, Euclid introduced the axiomatic method still used in mathematics today, consisting of definition, axiom, theorem, and proof.
