    13837 x 73 = 1010101

    For any 2-digit number, let's call it AB, if you multiply it by 1010101, you get ABABABAB.

    This trick only works if your age is between 10 and 99.

    also for ages 1 to 9
    so from 1 to 99 years of age
    when you are 100 or older, you get one bonus year !

    Yeah Frank, you are right, for an age 1 to 9 (let's call it A) you get A0A0A0A

    I found one that works with 3-digit age

    108911 x (your age) x 9191

    I Love Math ^_^
