No, it's an algorithmic computation.

It is an algorithm created in such a way that a different input will always produce a unique output that shall not be reproduced by other input, but as bit size are limited there is always a chance of equivalent output of different input (and it is not as simple as adding, in fact it must be secure enough as it store our password on most server and used as a digital signature/verification purpose). And no it is not only addition, infact there are many operation in it to make sure the result is always in constant bit size and unique (using addition will result in unique hash but not constant bit size), cmiiw.

Well, the existence of a collision isn't the end of the world, but if someone figures out how to manipulate the input such that a collision is forced to happen, the algorithm is pretty much useless.
