CHEFPRMS questions

nevermind i unerstand now

The description is correct! You’re interpreting it wrong. Compare it to a syntactically equivalent statement like “sum of two (not necessarily distinct) integers”. It’s clear what “not necessarily distinct” refers to.

Agree with @algmyr. Statement seems clear to me at least.

definition of not necessarily - possibly but not certainly - used to say that something is not definitely true. So what you said “sum of two ( possibly but not certainly distinct) integers” sounds like they could be distinct but dont have to be. Might have just said “… of two distinct primes”.

The two semi-primes you sum are possibly but not necessarily distinct, i.e. the semi-primes a and b that you sum to get a+b are allowed to be equal. Earlier in the problem description they explained exactly what they mean by semi-primes: “A semi-prime number is an integer which can be expressed as a product of two distinct primes.”
