you know, i forgot to show the guy that ask me this proof, lol, i guess he doesn't need it anymore. i'll ask him

here's another if you guys are bored (i'm doing this from memory, so pardon any errors, the same guy asked me this question, so if you guys have problems, i'll check with him to make sure i got the question right):

i actually thought up two ways to do this, but i ran into trouble at the punchline. here goes

let r be a rational number

let a be an irrational number

let s be a real number

Prove or disprove: either (ar + s) or (ar - s) is irrational
