In experimental sciences, the sign commonly indicates the confidence interval or error in a measurement, often the standard deviation or standard … A question mark symbol inside a circle. A version of the sign, including also the French word ou ("or"), was used in its mathematical meaning by Albert Girard in 1626, and the sign in its modern form was used as early as 1631, in William Oughtred's Clavis Mathematicae. 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 = +3 or x = −3. If you are new to ALT codes and need detailed instructions on how to use them, please read How to Use ALT Codes to Enter Special Characters. A more rigorous presentation of the same formula would multiply each term by a factor of (−1)n, which gives +1 when n is even, and −1 when n is odd.

For example, 230 ±10% V refers to a voltage within 10% of either side of 230 V (from 207 V to 253 V inclusive). which describes the two solutions to the quadratic equation ax2 + bx + c = 0. can be interpreted as a shorthand for two equations: one with + on both sides of the equation, and one with − on both sides. https://www.youtube.com/channel/UCmV5uZQcAXUW7s4j7rM0POg?sub_confirmation=1 How to type Plus Minus symbol in excel In mathematics, it generally indicates a choice of exactly two possible values, one of which is obtained through addition and the other through subtraction. If n = a ± b, any operation of the form m = f(n) must return a value of the form m = c ± d, where c is f(n) and d is range updated using interval arithmetic. A control character is a sequence of alphanumeric and special characters in the format . [7], For example, given the equation x2 = 9, one may give the solution as x = ±3. For the the complete list of the ASCII based Windows ALT Codes, refer to Windows ALT Codes for Special Characters & Symbols. In scientific usage, it sometimes refers to a probability of being within the stated interval, usually corresponding to either 1 or 2 standard deviations (a probability of 68.3% or 95.4% in a normal distribution). 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 5.7+0.2−0.1. Type %%c to place the capital letter O with a slash through it.
