That's an argument. If you don't accept the premise, then you don't accept the conclusion

thats for all math

why would you not accept infinite sets? It would take you pages to prove something thats obvious if you just used an infinite set

I'll always love Faustenberg's proof of the infinitude of primes using just point set topology. I also enjoy the Galois theoretic proof of the fundamental theorem of algebra, it's in Cox's book somewhere

(a+b)(a-b)=a^2-b^2
It's fucking awesome
(a+b)(a-b)=a(a-b)+b(a-b)=a^2-ba+ba-b^2
AND THEN -ba AND ba CANCEL OUT. THIS IS MINDBOGGLING.
(a+b)(a-b)=a^2-ba+ba-b^2=a^2-b^2
If this doesn't amaze you, you have no emotion
