Basic Arithmetic & Algebra Symbols

Basic Arithmetic & Algebra

These are the fundamental symbols used in everyday calculation and basic equations.

Symbol	Name	Meaning / Usage
$+$	Plus Sign	Addition ( $3 + 2 = 5$ ).
$-$	Minus Sign	Subtraction ( $3 - 2 = 1$ ) or negative numbers ( $-2$ ).
$\times$ or $\cdot$	Times Sign	Multiplication ( $3 \times 2 = 6$ or $3 \cdot 2 = 6$ ).
$\div$ or $/$	Division Sign	Division ( $6 \div 2 = 3$ or $6/2 = 3$ ).
$=$	Equals	Equality; values on both sides are the same ( $2 + 2 = 4$ ).
$\neq$	Not Equal	The values are not the same ( $2 \neq 3$ ).
$\approx$	Approximately Equal	Close to, but not exactly ( $\pi \approx 3.14$ ).
$\pm$	Plus-Minus	Both positive and negative operations ( $x = \pm 5$ ).
$\sqrt{x}$	Square Root	A number that produces $x$ when multiplied by itself ( $\sqrt{4} = 2$ ).
$	x	$
$n!$	Factorial	Product of integer and all integers below it ( $5! = 5 \times 4 \times 3 \times 2 \times 1 = 120$ ).
