6th is absurd ...

1) What is o^o ?

Undefined. Because any number raised to 0 is 1 and 0 raised to any number is 0.

2) What is 0/0?

Undefined. Because any number by 0 is infinity and 0 by any number is 0.

3) What is 0/infinity?

Can be defined as 0. Because 0/infinity is equivalent to 0/1/0 which is equal to 0/1 which is 0.

4) What is infinity/0?

Can be defined as infinity. Because infinity/0 is equivalent to 1/0/0 which is equal to 1/o which is infinity.

5) What is infinity - infinity?

Undefined. Because infinity - infinity is 1/0 - 1/0 which is (1-1)/0 which is 0/0 which is undefined.

6) 0 = 1 = infinity = 2 = 3 = 4............

Because,

infinity + infinity = 1/0 + 1/0 = 2/0 which is again infinity.

So infinity + infinity = infinity which means 2*infinity = infinity which means 2 = 1

Likewise, infinity + infinity + infinity = 1/0 + 1/0 + 1/0 = 3/0 which is infinity.

So infinity + infinity + infinity = infinity which is 3 = 1 or 2 = 0.

and so on.
