usually i would say '+', but it looks like you have strings, to do this:

var a = '034';
var b = '034';

var c = parseInt(a)+parseInt(b);
alert(c); //should alert 68

padre i didnt get 68. i got 56.

You're trying to add two octal numbers with the leading '0'
Try parseInt(a,10) instead.
See: http://www.w3schools.com/jsref/jsref_parseInt.asp

You could use the Number() function too:

var a = "034";
var b = "034";

alert( Number(a) + Number(b) );

That would eliminate any number base confusion on the browser's part, because the Number() function always assumes the number is base-10, unless the string passed to the number function starts with "0x". It always returns a base 10 number.

You can use parseInt() function also
var c = parseInt(a,10)+parseInt(b,10);
alert(c); //should alert 68
