Hey guys!
I've been working on this problem, but I just can't figure it out; it's probably easy, but I'm stuck on it. Here is the problem:

An alternative plan proposed a 4 digit area code and restricted the first and second digits. How many area codes would this plan have provided? I know the answer is 1600 but I can't figure out how they got that number. I've tried both nPr and nCr in every way I could think of , but I couldn't get the answer. What exactly am I supposed to do to solve the problem? Thanks!

is anything being carved off by the laser, how can 1s and zeros or on and off codes be repeatedly 'burned' into the same tracks over and over? Is digital information just a speeded up version of Morris Code?
