Although normal locks are fine for the 20th century, these Samsung touchscreen door locks show that you're a man that doesn't settle for last year's technology. These locks, which come in black and silver for $180 (170,000 Won), have a Samsung cellphone-esque touchpad for easy number entry, plus aluminum alloy and tempered glass for that extra bit of style. If we ever have anything worth protecting, we'd use one of these padlocks to do it. [AVING via Korean Gadgets via Coolest Gadgets]

@theimmc:

You're wrong. It works like this:

Possibility #1 = 0001

Ending Possibility = 4444

(In this case, because the guy wanted to know only 4 digits)

Thus, the formula would be the following:

N**xwhere N is the number of digits possible(here, 4 different digits arepossible)0 through 4

and x is the number of places available(here we have 4 places availablefor a 4 digit number)Note the formula is N raised to the x power meaning, 4**4 (4^4)

or 4 X 4 X 4 X 4 =
