Is there an algorithm that yields only prime numbers?
What exactly do you mean "yields only prime numbers"?
If you mean a formula that when given the numbers n=1, 2, 3, ... and so on generates the nth prime number (or a different prime number for each n) then no.
If you mean an algorithm whereby a number can be tested to be a prime number then yes.
(Using this prime_test algorithm, a simple algorithm can be written that would supply numbers one at a time to it and use its result to decide whether to yield the tested number or not, only yielding those numbers which pass the test.)
Which is are not consideration when reading math?
The mating practices of porcupines are not a consideration.
Does negative 2 correspond with 5?

1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 pretty much anything ending with 1 3 5 7 9
Prime numbers do not have any factors?
A prime number has two factors: one and the number itself. A prime number does not have any proper factors.

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97
Are All square numbers even numbers?
No; most are not, not even close. 2 is not a square, 6 is not a square, 8 is not a square, 10 is not a square, 12 is not a square, and 14 is not a square, just for starters.
Only a very small proportion of even numbers are squares: 4, 16, 36, 64, 100, 144, 196, 256, 324, 400....
