What's the goal? Do you want the number of distinct operation sequences that are valid, or do you want to find all the distinct results? Are the operations always performed left to right, or using order of operations with multiplication and division first?
You also need to avoid dividing by zero. (2 / 0 + 1 = wrong) You can model the concatenation of two or more digits into a multi-digit number as a fifth operator.
