The Not Equal Symbol, symbolized by ≠, is used to denote that two values or mathematical expressions are not equal to each other.

The Not Equal Symbol (≠) has applications in multiple disciplines:

Mathematics: Commonly used in algebra, calculus, and number theory.
Computer Science: Employed in programming languages for conditional statements.
Statistics: Used to denote inequality in statistical tests.
Engineering: Used in conditional logic within engineering models.

In spreadsheet software and programming languages, the "not equal" operator may be represented differently:

Google Sheets and Excel: Both commonly use the "not equal" operator represented as <>.
Python, Java, C/C++, and JavaScript: These programming languages represent the "not equal" operator as !=. In JavaScript, strict inequality can also be represented as !==.

Windows: Hold down the Alt key and type 8800 on the numeric keypad, then release the Alt key.
Mac: Press Option + =.
Linux: Press Ctrl + Shift + u, then type 2260 and press Enter.
HTML: Use the named entity ≠ or the numeric entity ≠.
LaTeX: To type the Not Equal Symbol in LaTeX, use the command \neq.
