Description: Negation is a mathematical function that involves inverting the sign of a number. In simple terms, if you have a positive number, negating it turns it negative, and vice versa. This operation is fundamental in mathematics as it allows for the manipulation and solving of equations, as well as understanding more complex concepts like symmetry on the number line. Negation is commonly represented with the ‘-‘ symbol in front of the number. For example, the negation of 5 is -5, and the negation of -3 is 3. This function applies not only to integers but also to fractions, decimals, and algebraic expressions. Negation is an operation found at the core of many mathematical areas, including algebra, arithmetic, and calculus. Additionally, it is essential for understanding concepts such as the additive inverse, where the sum of a number and its negation results in zero. In summary, negating a number is a basic yet crucial operation that allows mathematicians and students to manipulate and better understand numerical relationships.
