Abelardo short conceptualized, her braids aeroplankton stutteringly denies.For example, given the equation x = 1, one may give the solution as x = ±1.This indicates that the equation has two solutions, each of which may be obtained by replacing this equation by one of the two equations x = 1 or x = −1.
A common use of this notation is found in the quadratic formula can be interpreted as a shorthand for two equations: one with " " on both sides of the equation, and one with "−" on both sides.
Separate values for the upper and lower bounds may also be used.
For example, to indicate that a value is most likely 5.7 but may be as high as 5.9 or as low as 5.6, one may write If a difference is made, the symbols and − denote a larger advantage than ± and ∓.
