Besides, there is nothing difficult in realizing the way it goes. Say, in case you are going to go by subway there are maps of subway and those are very clear for people.
Say, you want to go somewhere and you want to go there by subway. In this case you will need a couple of dollars and a map of subway that is free and you can get it at any subway station. Though, it is important to remember that each district has its own subway map, so make sure that you have the right map of the right district and you will have no troubles.
In case you've made a decision to go the place you want by buss it will also take just a couple of dollars of you. Besides you may buy the Fun Pass and will have the free journey during a day or during a week or during a month. It depends on the Fun Pass you will choose. It is not difficult to realize the root of busses as those have peculiar names.
In case you want to get to the centre of the city you need to go by buss with "downtown" sigh and in case you need to go the opposite direction you need to go by the buss with "uptown" sigh. These are the main rules as for the transport and there is nothing difficult in those.
