Definition
-
A "negative number" refers to a mathematical symbol or value that expresses a quantity that is less than zero. In simpler terms, negative numbers represent values that are positioned to the left of zero on the number line. They are commonly denoted by placing a minus sign (-) in front of the number.
Negative numbers are primarily used in mathematics to describe situations involving a decrease, deficit, or loss. They are vital in various areas of study, including algebra, geometry, calculus, and statistics. Negative numbers provide a way to express below-zero temperatures, debts, losses, declines, decreases, or any value that falls short or is less than the baseline.
When operating with negative numbers, specific rules must be followed to perform accurate mathematical calculations. Addition and subtraction of negative numbers are interconnected, where the result depends on the signs of the numbers involved. Multiplication and division rules of negative numbers dictate that two negative numbers yield a positive product, while multiplying or dividing a positive number by a negative number produces a negative result.
Understanding negative numbers is fundamental in various aspects of real life, such as managing finances, calculating temperature variations, analyzing stock market investments, or interpreting statistical findings. By incorporating negatives into mathematical models, it allows for a more comprehensive understanding and representation of a wider range of scenarios.
Etymology of NEGATIVE NUMBER
The word "negative" used in mathematics comes from the Latin word "negativus", which is derived from the verb "negare", meaning "to deny" or "to negate". The concept of negative numbers was introduced in the 7th century by the Indian mathematician Brahmagupta, and their use spread to Europe during the 13th century. The term "negative" was used to describe these numbers because they were seen as opposite or "negated" versions of positive numbers.
