My reference to being 'cheated' was by myself of my own time. I jumped in convinced you had a solution with just the four arithmetic symbols and since the first part was relatively straight forward hit the poser with that in mind. Opening your mind to other symbols gives the number flexibility to 'solve' the problem in a variety of ways. I was just posing the question of which (of the 'solutions') people think may be the 'neatest' - that which could be done at the earliest age (I knew about sqr roots about 7 years before factorials)
