I will also talk about happy cube numbers, they are the same as happy numbers, but instead of squaring the digits of the original number, the digits are cubed. Furthermore, I will also explore happy prime numbers, these are prime numbers which are also happy. Additionally, I will mention unhappy numbers, these are numbers that do not end in 1 instead they loop in a cycle around number 4. Lastly, I will explore the history and real life uses of happy numbers, such as in computer programming and encryptions.

History of happy numbers The origins of happy numbers is not clear, the first time they were mentioned was during the 20th century. Likely guesses are that they originated from Russia. Reg Allenby a mathematics professor at Leeds university brought them to attention when his daughter showed them to him. Happy numbers usually were taught in schools, to younger children for fun. To show them something interesting in math. But nobody knows who first noticed and started telling people about happy numbers. But they never really left the classroom until Reg Allenby found out about them and started to show people what they were. Happy numbers Happy numbers are numbers that when you square the digits of the number and add the squares together repeatedly, in the end the answer will be one. This is how you can find a happy number: 19: 1²+9²= 1+81= 82 8²+2²= 64+4= 68 6²=8²= 36+64= 100 1²+0²+0²=
