To determine if 3 is a happy number or unhappy number, we square each digit in 3 and then add those numbers together.
  
Then we repeat the process for the result until either the result turns to 1 or we realize it will never be 1.
  
If it becomes a 1, then it is a happy numbers. Otherwise, it is an unhappy number.
  
Here is the math to make it more clear:
  
32 = 9
  92 = 81
  82 + 12 = 65
  
We kept doing the math above and it just started looping the same numbers and never got to 1. Since, we did not get to 1,
3 is an: 
  
Unhappy Number
