Have you tried eval ? 

eval("4+5-6*1") -> 3

Hi Hamza,

You can get result using string function like split function and after you get individual object do your calculation.

  • thanks but i have have used split function, i was wondering if there is another function ,like parsing, which directly gives you the arithmetic expression or result.. as it is a calculator it can get any combination of operators..
