Math is weird. Consider, if you will, that you have infinity. Now if you take this infinity, and add another infinity to it, it's still infinity. Same goes for Multiplication. Infinity to the second power is still infinity.
Now it gets really weird. Say you've added your two infinities together. Now you want to subtract an infinity from this infinity. But instead of getting infinity, you get only one number, (Infinity is more of a concept of numbers, rather than just one, which is why I'm verifying this).
And it can be ANY possible number. Infinity minus Infinity is equal to 7 or 156 or one third. And once again the same thing applies to Division.
And this is why Math is weird.
