    I don’t think this one will work. I tried it on every smartphone I can think of (and non-smartphones as well) and the ‘secret’ number still appears before I hand it to my friend.

    It was fine until you got the multiply part, then the hidden number reappeared.
    But a similar trick might work with addition/subtraction like the usual number tricks.
