\n" ); document.write( "I have a question for example\r

\"%281%2F2%29+%2A+4%28-+2%29%5E2\" is correct since you have to SQUARE the value of y, which is - 2. \r
\n" ); document.write( "\n" ); document.write( "First expression: \"%281%2F2%29+%2A+4+%2A+-+4\" ------> \"2+%2A+-+4\" ------> \"-+8\".
\n" ); document.write( "Second expression: \"%281%2F2%29+%2A+4+%2A+4\" -------> \"2+%2A+4\" --------> \"8\".
\n" ); document.write( "Do you see the difference? \n" ); document.write( "
\n" );
