A mathematician was bored during a long train ride fomr Upstate New York to New York City. Having a little notebook nad pencil always handy, she began to scribble:

21(squared)-12(squared) = 441-144=297

31(squared)-13(squared) = 961-169=792

41(squared)-14(squared)=???

342(squared)-243(squared)=???

1. What is the mathematician invetigating here?

2. Can you find pattern when you continue her investigation for 2 digit or 3 digit numbers? For numbers with any amount of digits?

3. The differences above(297 and 792) are divisible by 99. what ahot the differences of reversed squares for any 2 or 3 digit or any number with any digits?
