What Does the "±" Symbol Mean in Mathematics?
Definition of "±"
The "±" symbol stands for "plus or minus." It indicates that there are two possible values: one obtained by adding the number after the symbol, and the other by subtracting it. This notation is prevalent in various branches of mathematics, including algebra, calculus, and statistics.For example:
- If you see x = 5 ± 2, it means:
- x = 5 + 2 = 7
- x = 5 - 2 = 3
Common Uses of "±"
- Solving Quadratic Equations: The quadratic formula involves "±" to account for two solutions.
- Expressing Uncertainty: In measurements, "±" indicates a margin of error or uncertainty.
- Statistics: To denote confidence intervals or standard deviations.
