Thank you! I've read these but there's no information on exactly how to calculate it. They say to use the Pythagoras theorem. I know how to use it, but what values? The values in the boxes (10, 100, etc.) or the amount of steps I take?
If I start in the upper right cell (value 10) and I go two steps down, and one step to the left. I will end up at 100. Where do I go from here?
