This is a calculator to find the sum of a non-negative series. By that, I mean each next term is the non-negative (positive or zero) difference of the last two. This sums the sequence up to however many terms you want and displays the term on the left side. Sorry, the list on the side only displays up to the 200000th term.
I made this project to help me get a better understanding of a math problem involving this series. (I'm still stumped, and it's due tomorrow when I'm writing this. Oh well.)
