In mathematics, the equal sign can be used as a simple statement of fact in a specific case ( x = 2), or to create definitions ( let x = 2), conditional statements ( if x = 2, then. Usage in mathematics and computer programming The symbol || was used by some and æ (or œ), from the Latin word aequalis meaning equal, was widely used into the 1700s" ( History of Mathematics, University of St Andrews). "The symbol = was not immediately popular. Fire up your Word or Excel, or PowerPoint document.- And to avoid the tedious repetition of these words: "is equal to" I will set as I do often in work use, a pair of parallels, or duplicate lines of one length, thus: =, because no 2 things can be more equal.If you want to insert the Symbol for Not Equal To in Microsoft Word, Excel, or PowerPoint, follow the instructions below.
