Try to see if you can do the math

8	3
4	7
3	9
8	5
2	6
5	9
6	6

</body>

<pre lang="Javascript">

<pre>		(function( math )  { 
				   'use strict';
				   var tr = math.querySelectorAll( 'tr' ), 
					   td = math.querySelectorAll( 'td' ), 
					  inp = math.querySelectorAll( 'input' ),
				   totals = [], c;
			   for ( c = 0; c < tr.length; c ++ ) {
					 totals.push( parseFloat( td[ c * 3 ].textContent ) + 
								  parseFloat( td[ c * 3 + 1 ].textContent ) );
					 inp[ c ].value = ' ';				   
					 inp[ c ].addEventListener( 'blur', check_answer( c ), false );

				}

		function check_answer( c ) {
			   inp[ c ].onblur = function() { 
				  if( inp[ c ].value == totals[ c ] ) {
					  tr[ c ].classList.add( 'right' );
					 }
						  else {
				 tr[ c ].classList.remove( 'right' );

							 }
						  }			   
					   }
		 }( document ) ); 

$( window ).unload(function(math) {
});

querySelectorAll is just $, so $("tr") and addEventListener is "on". You could even replace the loops with "each". Look at the jQuery docs, they're quite extensive with examples.

Is this even close

$(totals) = [], c;
$('tr','td','input'){
each(( c = 0; c < tr.length; c ++ ) {
totals.push( parseFloat( td[ c * 3 ].textContent ) +
parseFloat( td[ c * 3 + 1 ].textContent ) );
inp[ c ].value = ' '; } )
onblur('blur', check_answer( c ), false )
};

$(check_answer(c)){
onblur( if( inp[ c ].value == totals[ c ] ) {
tr[ c ].classList.add( 'right' );
}
else {
tr[ c ].classList.remove( 'right' );
tr[ c ].classList.add( 'wrong' );
})
};

$( window ).unload(function(math) {
});

Why do you need to use jquery? jQuery IS javascript. I do like it but you don't have to use it.

Use "Reply" widget to be sure that system will inform member about your reply.
You'll find that widget on the right side of member's nick/login.
