Help

Hi guys,

If any of you guys have experience with number theory/proofs, I'd really appreciate your help with some of my math camp problems! They are so hard, I'm not even sure where to start

oh i have experience

wait is it ross?

i can help

what expiriance??????????

experience with number theory

Thanks @LLLhk, yes it is ross

This is the problem

These are the axioms we have to work with

Actually I think I got this one

hint : proof by contradiction 

i guess i was sleeping when you sent this xD

woah...what grade r u guys in? I don't even know what any of it means... O-O

high school

it uses set theory

Yes, high school as well. Though none of this (including number theory, set theory) is taught in standard US curriculum, you can only find it in US math competitions and programs. Perhaps it is taught in China, I'm not quite sure

we learn basic set theory in first year of high school, but i don't think number theory is taught (and yes basically number theory is used in competitions: like I guess Modular Arithmetic, Chinese remainder thm, lift the exponent, zgimondy, orders, dirichlet, and quadratic reciprocity are all stuff you can expect from the chinese TST)

oh makes sense, .we are supposed to learn all this next year >< 

Wait, aren't you in high school @Hobi_Mochi?

welp I am but in our country's syllabus...set theory and all r taught in 11th ...

you from india????

when i search set theory 11th grade all i get is India cirriculum
