I just wrote a big numb addition function this morning, it is a bit silly and naive, not pure string not pure integer. I think it is correct, but i may have missed leading last digit.

Suggestions to write it shorter and more clear, but keeping the naive approach appreciated.

<SCRIPT LANGUAGE="Javascript">

function naiveAdd(strOne,strTwo) {
if (strOne.length>=strTwo.length) {length=strOne.length;} else {length=strTwo.length;}
oneS = strOne.split("").reverse().join("");
twoS = strTwo.split("").reverse().join("");
out="";
remainder=0;
for (i=0;i<length;i++){
         one=oneS.charAt(i);
         two=twoS.charAt(i);
         one=parseInt(one);
         two=parseInt(two);
         if (isNaN(one)) one = 0;
         if (isNaN(two)) two = 0;
         sum=one+two+remainder;
         if (sum>=10) { sum=sum-10; remainder=1;} else {remainder=0;}
         out=sum+out;
    }
document.write("Sum = ",out,"<BR>");
}

strOne="9003";
strTwo="13039";
naiveAdd(strOne,strTwo);

</SCRIPT>
