help me with this lmao-​

Answer 1

Answer:

1. Sometimes the set of primes is denoted by P. However, this notation is not standard enough that you can use it without clarifying it, such as by saying "we denote the set of prime numbers by P."

1. Alternate notations which are sometimes used would be P (this is a common way to bold letters in math literature), PRIMES (mostly in CS), or |Spec(Z)| (among arithmetic geometers, although it's unnecessarily complicated unless its in the context of a generalizable statement about rings of integers in a number field or something); the last one would perhaps require furtherclarification that if X is a scheme then |X| denotes its set of closed points.
