I am studying for a test on Monday,

I am making myself problems and I don't know how to do this one.

How many ways are there to get from A to B?

The middle is a "pond" and there are pathways on all sides of the pond.

2. Relevant equations

I ussually do these with permutations, for example of there is a grid in which you have to travel down 8 and right 5 I find out how many distinct permutations there are of DDDDDDDDRRRRR and that is the answer. Of course this only works for simple pathway problems and is useless in this scenario.

I know that I will be facing problems like this on my test so I need a better strategy, can someone help me find one?
