The English mathematician, John Wallis (1616 – 1703) is credited with giving some meaning to negative numbers by inventing the number line, and in the early 18th century a controversy ensued between Leibniz, Johan Bernoulli, Euler and d’Alembert about whether \log (-x) was the same as Log(x).
What cultures were the first to use negative numbers?

An integer can be written as a fraction by giving it a denominator of one, so any integer is a rational number. A terminating decimal can be written as a fraction by using properties of place value. For example, 3.75 = three and seventy-five hundredths or 3 75 100 , which is equal to the improper fraction .

What are the characteristics of negative numbers?
And these are: 1 A negative number is a number that is less than zero 2 Numbers that are to the left of zero on the number line 3 A number that is the opposite of a positive number 4 A negative number represents loss or absence of something. 5 A quantity that has a direction
What is the difference between nonnegative and nonpositive numbers?
Because zero is neither positive nor negative, the term nonnegative is sometimes used to refer to a number that is either positive or zero, while nonpositive is used to refer to a number that is either negative or zero.
