Homonym: − (Negative)
The symbol "−" represents subtraction in mathematics. It indicates the operation of taking one number away from another. For example, in the equation 5 − 2 = 3, the "−" shows that we are removing 2 from 5, resulting in 3. This operation is fundamental in arithmetic and helps us understand how quantities relate to each other.
In addition to subtraction, the "−" symbol can also denote negative numbers. For instance, −4 represents a value that is four units less than zero. This concept is essential in various fields, including finance, where negative values can indicate debt or loss. Understanding "−" is crucial for solving many mathematical problems.
