You can put this solution on YOUR website!
Multiplying the number $\"7%2F9\"$ times $\"1\"$ you get the number $\"7%2F9\"$ .
\n" ); document.write( "The same happens with any whole number, any integer, any rational number, any number of whatever kind you know about.
\n" ); document.write( "In your class it may be called \"Multiplicative Identity\" property,
\n" ); document.write( "or \"Identity Property of Multiplication\", or some such thing.
\n" ); document.write( "Unfortunately, different people call it slightly different names.
\n" ); document.write( "When you take any number, and you multiply it times $\"1\"$ ,
\n" ); document.write( "the result is identical to the number you started with.
\n" ); document.write( "The number $\"1\"$ is the identity element (number) for multiplication.
\n" ); document.write( "The number $\"0\"$ is the identity element (number) for additions,
\n" ); document.write( "because you can add $\"0\"$ to any number, and you get the number you started with.
\n" ); document.write( "Math people like that, and in fancy math courses the same ideas get generalized to more abstract applications, with more words to remember,
\n" ); document.write( "but whatever they call a set, its elements, and the operations,
\n" ); document.write( "when you have a set of elements
\n" ); document.write( "(like the rational numbers, for example),
\n" ); document.write( "and you define an operation that can be done with two elements of that set,
\n" ); document.write( "it is cool to have an identity element. \n" ); document.write( "

\n" );
