Please follow the other thread. There you will find good reasons for 0^0 = 1.
]]>To see why 0 is the same as -0 and +0, imagine +1, +2, and so on, as a line starting from zero, like this:
A negative number is the same as a positive number, except you reverse the line. It's Stays the same length and still starts at zero, but it's flipped. For example, -2 looks like this:
You can imagine "flipping the line" with numbers closer and closer to zero (shorter and shorter lines). But what happens when your line gets so short that it doesn't really have length? (You could say "0 length").
By that stage, you don't really have a line anymore. You have a point which represents zero:
Because it doesn't have any length "flipping" it doesn't change it, so +0 is the same as -0.
