    If I buy a certain 4 items priced at:
    $1.20
    $1.25
    $1.50
    $3.16

    To get the total of these figures, it does not matter
    if the prices are added together as one would expect or
    if the prices are multiplied. The total bill will be the
    same: $7.11. What mathematical principle is being
    displayed in this problem?

    1.20 * 1.25 * 1.50 * 3.16 =
    (((3.16 + 50% ) + 25% ) + 20% )=
    3.16 + 1.58 + 1.185 + 1.185=
    3.16 + 1.58 + 1.18 + 1.19=
    3.16 + 1.50 + 1.20 + 1.25

    Ehm...percentage calculation? Dunno, seems to me that it's simply lucky.
