what is the triple equal sign mean?
Mar 23, 2012 #3. When you see a three bar equal sign it means by definition it is equal to something. For instance you could say x=3 and that would be for a particular circumstance. But when you say for instance, Ampere's law, â«B dot ds, that is by definition(three bar equal sign) equal to current enclosed multiplied by Î· naught. Likewise greater than or less than signs with two bars underneath mean it is greater or less than by definition.
