Answer 9

Any infinite set, such as the set of positive integers, is still infinite in size after adding 4.

Answer 10

I thought that there was some secret cool math thing to it or something

Answer 11

Not that infinity isn't cool

Answer 12

Two infinite sets are said to be the same size if you can match up all the members of those sets with a one to one correspondence without leaving any members out of either set

Answer 13

how did you do the sideways eight thing

Answer 14

Well, what if you do leave members out? Or don't match it up 1 to 1?

Answer 15

the sets could still match, perhaps as ordered pairs

Answer 16

Just because you have one less number in one of these infinite sets doesn't mean you can't match them up one to one, it just means each number from the first set will always be matched up with a number one larger.
