If d string is fixed then one can use like this string s = "(((5+6+4)/15)*100)"; int int1 = Convert.ToInt32(s.Substring(3, 1)); int int2 = Convert.ToInt32(s.Substring(5, 1)); int int3 = Convert.ToInt32(s.Substring(7, 1)); int int4 = Convert.ToInt32(s.Substring(10, 2)); int int5 = Convert.ToInt32(s.Substring(14, 3)); int ans = (((int1+int2+int3)/int4)*int5);

That's great!! I wonder if you can write the same logic for... string s = "(((15+16+14)/115)*1100)"; and what about string s = "(((-5+6+4)/15)*100)"; :)

This is not like that. This is an Infix string. First of all you need to convert into of PostFix or Prefix to perform the calculation as the computer does internally. For that you can simply use Data Structure like Stack or Tree.
