\r\n" );
document.write( "We move from left to right and make operation in parentheses, first :\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    (1*2) = . -  = 3 - 2 = 1.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "using the definition.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then we make next operation \r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    (1*2)*3 = 1*3 = we use the definition, again = . -  = 3 - 3 = 0.    ANSWER\r\n" );
