Oct 20, 2012 · The minus sign has three main uses in mathematics: The subtraction operator: A binary operator to indicate the operation of subtraction, as in $5 − 3 = 2$. Subtraction is the inverse of addition. Directly in front of a number and when it is not a subtraction operator it means a negative number. For instance $−5$ is negative $5$.

Among the most universally recognized symbols in mathematics is the − symbol, representing the "Minus Sign". This simple yet profound symbol finds application across a spectrum of mathematical operations and contexts. This short lesson covers the diverse uses of the − sign and offers illustrative examples for clarity. Usage

This notation looks like “a−b=−b” or “2 + ⁻3 = ⁻1”. It isn’t the only notation that’s been used. You may recall that two weeks ago we saw that DeMorgan represented negative numbers by a bar over the number, as seen here (p. 46): His 4¯¯¯ wouldn’t work so well as an operation, but was a reasonable attempt to distinguish negation from subtraction. Th...
This definition of subtraction as “adding the opposite” can’t be used before students have learned about negatives, or in contexts dealing only with natural numbers. There, we define subtraction as the inverse operation of addition. That is, the difference a−b=c is the (unique) number c such that a=b+c. Subtraction “finds the missing addend”. This ...
I did some searching of my own, hoping to find examples of the raised negative in modern materials; but at the time that was hard to find; the only source I found no longer exists. It is easier to find references to it today; one reference I find to it, here, says Wikipedia mentions it (here) without citation. American teaching standards don’t ment...
Minus Symbol. The minus symbol (−) is a mathematical symbol used primarily to denote the operation of subtraction and to indicate negative values. In mathematics, it serves as a critical tool for expressing the removal of one quantity from another, as in equations such as (5 – 2 = 3).

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.
