What is ±?


A symbol meaning "plus or minus" (or "give or take"), ± is used to denote the uncertainty in the value of a figure. It is primarily used in Physics experiments to account for any inaccuracy in the measuring/readings and any random errors that can occur which may affect the results obtained. However, it is also used in Engineering, Medicine, Chemistry, Mathematics and pretty much anythingwhere numbers and/or experimentation are used.
