ELI5: Explain Like I'm 5

Newton polynomial

Newton polynomial is like a jigsaw puzzle. You start off with a bunch of jigsaw pieces (numbers). Even if the pieces don't seem to fit together, you can still make something out of them. With a Newton polynomial, you connect the pieces together to make a line. That line can be used to explain a pattern or trend in the numbers. The line is like the puzzle that the pieces fit into.
