say there is a theoretical highest number. call it n. but n+2=2 higher than n. correct? but say n=infinity. n+2=n. this is because infinity is always higher. since it is always higher, 2 is just another addition to infinity. infinity is always getting higher. infinity+infinity=infinity. but what about infinity divided by infinity? is it not 0? and also, take any number divided by infinity. what do you get? 0.0000000.......0000000001. infinite zeros, than one. if the zeros are infinite, how can you get the one at the end?does the 1 keep getting pushed back forever? and what is 2 - infinity? it is negative infinity. infinitly far away from zero, and infinitly away from any other number, even if it is negative. because infinite is not bigger. just farther away from the number line, whatever the direction.
