document.write( "In other words, there are TWO different functions practically under the same name.\r\n" );

document.write( "So, without the context,    is not a single value or a function. \r\n" );

document.write( "\r\n" );
document.write( "Only if and when the context is EXPLICITLY (or IMPLICITLY) DEFINED, it becomes one function or one single value.\r\n" );

document.write( "\r\n" );
document.write( "Professional mathematicians \"feel\" the context practically with no error, but for the school people (students or/and teachers) \r\n" );
document.write( "it is often difficult to feel the context.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Therefore in school Math nobody and never explains it, because this understanding gains only with experience.\r\n" );
