Question: where are negative numbers used in real life

title: Negative number
text: In mathematics , a negative number is a real number that is less than zero . Negative numbers represent opposites . If positive represents a movement to the right , negative represents a movement to the left . If positive represents above sea level , then negative represents below sea level . If positive represents a deposit , negative represents a withdrawal . They are often used to represent the magnitude of a loss or deficiency . A debt that is owed may be thought of as a negative asset , a decrease in some quantity may be thought of as a negative increase . If a quantity may have either of two opposite senses , then one may choose to distinguish between those senses -- perhaps arbitrarily -- as positive and negative . In the medical context of fighting a tumor , an expansion could be thought of as a negative shrinkage . Negative numbers are used to describe values on a scale that goes below zero , such as the Celsius and Fahrenheit scales for temperature . The laws of arithmetic for negative numbers ensure that the common sense idea of an opposite is reflected in arithmetic . For example , − ( − 3 ) = 3 because the opposite of an opposite is the original thing . 

Answer: answer: In real life, negative numbers represent opposites. For example, if moving to the right represents positive, negative represent moving to the left, if above sea level is positive, then below sea level is negative, and if a deposit is positive, then a withdrawal is negative. An expansion could be though of as a negative shrinkage in the medical field. Negative often represents the magnitude of a loss or deficiency, so a debt can be a negative asset. Negative also represents values on a scale that are below zero.
answer: In real life, negative numbers represent opposites. Negative numbers are used to describe values on a scale that goes below zero , such as the Celsius and Fahrenheit scales for temperature .
