ELI5: 64bit and 32bit. What are the pros and cons of each? Why is tech moving towards 64bit?

Really like you are 5? 

64 bit can do math on bigger numbers, it can do math on smaller numbers(more precise), and it can memorize more things. 

32 bit is cheaper and lower power that is it (for those of you that are going to argue that memory savings are another advantage, what does memory cost?)

High end cpus are moving towards 64 bit because going faster got a lot harder around 2003 so going wider was cheaper and almost as effective.
