    How it works:
    (n * 2 + 5) * 50 + 1760 – year born (- 1 if you haven’t had your birthday) = n * 100 + age

    n * 100 + 250 + 1760 – year born (- 1 if you haven’t had your birthday) = n * 100 + age

    (n * 100) + [2010 - year born (- 1 if you haven't had your birthday)] = (n * 100) + (age)

    (n * 100) + (age) = (n * 100) + (age)

    The reason the annotations had to be added in was because the equation in the video was only true when it was uploaded, last year.
