Enumerable#inject with a symbol argument and no block calls the method represented by the symbol on the first element of the enumerable, with the second element as the argument. It takes the result of that and calls the method represented by the symbol on it, with the third element as the argument. It repeats this process until there are no elements left in the enumerable.
