What Is The Plus-Minus (±)?

The Plus-Minus symbol (±) is a widely used mathematical sign representing two possible positive and negative values. It&#;s typically read as &#;plus or minus&#; and appears in uncertain or variations scenarios.

For example, in algebra, the square root 81 is written as √81 = ±9, meaning the result could be either +9 or This symbol also helps express ranges or approximate values.

How to Type the Plus-Minus Sign (±)

Typing the plus-minus sign is simple on different platforms:

• Windows: Hold Alt, type  on the numeric keypad, then release Alt.
• Mac: Press Option + Shift + =.
• Linux: Press Ctrl + Shift + u, type 00B1, then press Enter.
• HTML: Use ± or &#;.

  What is the Plus Minus Symbol?

  The Plus Minus Symbol (±) is a mathematical notation used to indicate a range of values around a central value. It represents the concept of "plus or minus" and is commonly used in various fields such as mathematics, science, and engineering. For instance, in measurements and calculations, the Plus Minus Symbol denotes the uncertainty or tolerance of a value, showing that the actual value could be either slightly higher or lower than the stated value.

  Why Use the Plus Minus Symbol?

  There are several reasons to use the Plus Minus Symbol:

  • Indicates Range: The Plus Minus Symbol is essential for showing that a value can vary within a specified range. This is crucial for precision in scientific experiments, engineering tolerances, and mathematical calculations.
  • Represents Uncertainty: In measurements and statistics, the Plus Minus Symbol helps to convey the degree of uncertainty or error associated with a value, allowing for more accurate data interpretation.
  • Enhances Clarity: By using the Plus Minus Symbol, you can clearly communicate the range of possible values,

    The plus–minus sign or plus-or-minus sign (±) and the complementary minus-or-plus sign (∓) are symbols with broadly similar multiple meanings.

    Other meanings occur in other fields, including medicine, engineering, chemistry, electronics, linguistics, and philosophy.

    History

    [edit]

    A version of the sign, including also the French word ou ("or"), was used in its mathematical meaning by Albert Girard in , and the sign in its modern form was used as early as , in William Oughtred's Clavis Mathematicae.^[1]

    Usage

    [edit]

    In mathematics

    [edit]

    In mathematical formulas, the ± symbol may be used to indicate a symbol that may be replaced by either of the plus and minus signs, + or −, allowing the formula to represent two values or two equations.^[2]

    If x² = 9, one may give the solution as x = ±3. This indicates that the equation has two solutions: x = +

    The plus sign (+) and the minus sign (−) are mathematical symbols used to denote positive and negative functions, respectively. In addition, + represents the operation of addition, which results in a sum, while − represents subtraction, resulting in a difference.^[1] Their use has been extended to many other meanings, more or less analogous. Plus and minus are Latin terms meaning "more" and "less", respectively.

    The forms ⟨+⟩ and ⟨−⟩ are used in many countries around the world. Other designs include ⟨﬩⟩ for plus and ⟨⁒⟩ for minus.

    History

    [edit]

    Though the signs now seem as familiar as the alphabet or the Hindu–Arabic numerals, they are not of great antiquity. The Egyptian hieroglyphic sign for addition, for example, resembled a pair of legs walking in the direction in which the text was written (Egyptian could be written either from right to left or left to right), with the reverse sign indicating subtraction
