Introduction to Plus or Minus Symbol in LaTeX
The plus or minus symbol, denoted as \pm, is a mathematical symbol used to indicate that a value can be either positive or negative. In LaTeX, a typesetting system used for creating documents, the plus or minus symbol can be represented using the \pm command.
Basic Usage of Plus or Minus Symbol in LaTeX
To typeset the plus or minus symbol in LaTeX, you can use the \pm command. For example, the code $a \pm b$ will produce the output a \pm b. This symbol is commonly used in mathematical expressions to denote the range of values or to indicate that a value can be either added or subtracted.
Advanced Usage of Plus or Minus Symbol in LaTeX
Besides the basic usage, the plus or minus symbol can be used in various mathematical contexts. For instance, it can be used to represent the range of values in an inequality, such as $x \in [-1, 1]$, which denotes that x can take any value between -1 and 1, inclusive.
Typesetting Plus or Minus Symbol with Other Mathematical Operators
When typesetting mathematical expressions involving the plus or minus symbol along with other operators, it’s essential to follow the correct order of operations and use the appropriate spacing. For example, the expression $a \pm b \times c$ should be typeset as $a \pm (b \times c)$ to avoid ambiguity.
| Mathematical Expression | LaTeX Code |
|---|---|
| $a \pm b$ | `$a \pm b$` |
| $x \in [-1, 1]$ | `$x \in [-1, 1]$` |
| $a \pm (b \times c)$ | `$a \pm (b \times c)$` |
