    Very reminiscent of when our Algebra teacher asked us to expand (x-a)(x-b)(x-c)…(x-z)

    The answer is 0. This is the funniest mathematical puzzles I’ve ever dealt with

    Thanks Gennardo.
    At first I was like, no it can’t be 0, I can make it 1 if for every letter I put … and then it hit me LOL.
    Cute puzzle indeed.
