This is another great implementation task. There is not much to say but I will try to give a few tips. First of all I suggest finding the numbers first and storing them somewhere then proceed to the operations. Here is how we do that, we loop over the string, whenever we see a digit we make another loop until we see the end of that number, then we turn the found area into an integer and store it somewhere. After making those steps no its time to loop over the string again this time looking for the arithmetic operations. Check the source code for a better understanding.
