to separate the negative numbers and the positive numbers on a number line
Negative numbers were first recorded in ancient China, where they appeared in the Han Dynasty around the 2nd century BCE, primarily in the context of accounting and mathematics. The Chinese used red rods for positive numbers and black rods for negative ones. While other cultures, such as Indian mathematicians, also recognized negative numbers later on, it is China that is credited with their earliest documented use.
No. Whole numbers are counting numbers and zero.
Yes, the mean of a set of negative numbers is always negative. The mean is calculated by summing all the numbers and then dividing by the count of numbers. Since all the numbers in the set are negative, their sum will also be negative, resulting in a negative mean.

The concept of negative numbers was first documented by Chinese mathematicians around the 2nd century BC. These numbers were initially used to solve practical problems related to debt and payments.
The product of three negative numbers is negative.
They will be negative numbers as for example -5+(-7) = -12
One source says that a Chinese text (Nine Chapters in the Mathematical Arts) from around 200 BC used red rods for positive numbers and black for negative. So the "inventor" must be older than that. European texts up until the Renaissance considered negative numbers as absurd.

Where do we see negative numbers
Yes, the mean of a set of negative numbers is always negative. The mean is calculated by summing all the numbers and then dividing by the count of numbers. Since all the numbers in the set are negative, their sum will also be negative, resulting in a negative mean.
It belongs to the set of negative rational numbers, negative real numbers, fractionall numbers, rational numbers, real numbers.
No, not all negative numbers are rational. There are many negative numbers that are irrational, just like the positive numbers.
