What is the significance of a negative number?

In mathematics, a negative number represents an opposite. In the real number system, a negative number is a number that is less than zero. Negative numbers are often used to represent the magnitude of a loss or deficiency.

What is the physical meaning of negative?

A negative number is the additive inverse of a positive number. a + b = 0 implies a = -b. Now all you have to do is find a physical interpretation of a number a, and a physical interpretation of addition, and a physical interpretation of zero, and then you have a physical interpretation of a negative number.

What is the importance of knowing positive and negative integers in real life?

Real-life situations can be calculated in integer value as well. Integer value is either positive or negative for real life situations. Positive numbers show the goodness, happiness, togetherness, and well-being whereas negative numbers show dullness, sadness, low feeling, etc.

How are negative numbers used in real life?
