if the given number is 3a, then twice the given number is 2 * 3 * a = 6 * a = 6a\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "keep in mind that 3a is really a short hand version of 3 * a, where * is the multiplication symbol.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "twice * 3a is 2 * 3a which is 2 * 3 * a.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "based on the asociative law of multiplication, 2 * 3 * a is equivalent to 2 * (3 * a) and also equivalent to (2 * 3) * a.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "in that last form, it becomes 6 * a which becomes 6a when shown in the shorthand notation.\r
\n" ); document.write( "
