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.
Subtraction (which is signified by the minus sign −) is one of the four arithmetic operations along with addition, multiplication and division. Subtraction is an operation that represents removal of objects from a collection.
When a minus sign is used in between two numbers, it represents the binary operation of subtraction. When a minus sign is written before a single number, it represents the unary operation of yielding the additive inverse (sometimes called negation ) of the operand.
The plus–minus sign, ±, is a symbol with multiple meanings: In mathematics , it generally indicates a choice of exactly two possible values, one of which is obtained through addition and the other through subtraction .
÷ (division sign) Widely used for denoting division in Anglophone countries, it is no longer in common use in mathematics and its use is "not recommended". [1] In some countries, it can indicate subtraction.
Use the minus sign to subtract keywords from the results. If you only want to see some search results and not others, you can specify keywords to exclude from the results. Note that the...
The hyphen-minus symbol -is the form of hyphen most commonly used in digital documents. On most keyboards, it is the only character that resembles a minus sign or a dash so it is also used for these. The name hyphen-minus derives from the original ASCII standard, where it was called hyphen–(minus).
If each subtraction is replaced with addition of the opposite (additive inverse), then the associative and commutative laws of addition allow terms to be added in any order. The root symbol √ is traditionally prolongated by a bar (called vinculum ) over the radicand (this avoids the need for parentheses around the radicand).
The two widely used arithmetic symbols are addition and subtraction, + and −. The plus sign was used by 1360 by Nicole Oresme in his work Algorismus proportionum. It is thought an abbreviation for "et", meaning "and" in Latin, in much the same way the ampersand sign also began as "et".
Elementary arithmetic is a branch of mathematics involving basic numerical operations, namely addition, subtraction, multiplication, and division. Due to the low level of abstraction, broad range of application, and position as the foundation of all mathematics, elementary arithmetic is generally known as the first branch of mathematics that is ...
