I have a 1x8 board...
My professor gave us this problem that says that we have a 1x8 board and we have dominoes that are 2 units long and squares that are one unit long. how many different ways can you tile the the board?
If you can help me just know what formula/method to use to solve this problem in any 1xn or mxn board that would be great thanks so much

Since this is a challenge for you from your professor I will not give you the answer outright, but I will give you a hint.
Think about the Fibonaaci numbers. Do you know what they are?.

yea....
yeah they are the two previous numbers added together to get the next number so f sub 1 is 1 and f sub 2 is 1 and f sub 3 is 2 then it goes, 3,5,8,13 etc.. so now wut?

1by1 can only be tiled in 1 way. Right?. Because of the one square.
1by2 can be tiled 2 ways: either two squares or one domino.
1by3 can be tiled 3 ways: three squares, or a domino and square, or a square and domino.
1by4 can be tiled in 5 ways. And so on and so forth.
See the pattern?.
