Here you go. This is basic math.
The X's represent a number divided by itself. Hence the one. 0 represents zero.
If you take a number and divide it by itself, you get one (the centerline of 1) But math says that you can't divide by zero. But if you divide zero by zero, you get one.
If you go from the top right instead of bottom left, you get -1 and so forth.
