The Blinds and Poker Maths

Hi,
Just want my understanding confirmed. Preflop (small and big blinds are late positions). Postflop (small and big blinds are early positions). Also where is a good place for a beginner to study poker maths?
Thanks, Archie.

Check out on YouTube, search for "Pot odds and equity". You'll come across plenty of videos, go over a few since different YouTubers have different ways of showing you and presenting examples.
