    Ah, you see, I think it might be Aquarion\’s 28th birthday.

    If this is some kind of maths puzzle that has nothing to do with birthdays then I\’ve got no idea what it means.

    28!

    No. Not 28. You may be taking the meaning of significant too literally.

    25.
    25*25=625

    25/5=5.

    Happy birthday.
