Ultimate integer addition and multiplication most stupid method

Using system.text; private string addnumber (string numa, string number) {int LENA = 0, lenb = 0; int Leni = 0, INTTEN = 0; int = 0, INTB = 0; stringbuilder result = new StringBuilder (" "); Lena = Numa.Length; lenb = Numb.length; if (lena> lenb) leni = lena; else leni = lenb; for (int i = 0; i 0) Result.insert (0, Convert.TOString (intten)); Return Result.toString ();

Private string Multinum (string numa, string number) {int LENA = 0, lenb = 0; int LENI = 0;

String result = "0"; string addresult = "0"; int dig = 0;

LENA = Numa.length; lenb = Numb.length; if (lena> lenb) {leni = lenb; for (int i = 0; i
