Believe it or not one of my degrees is actually in Math so it doesn't scare me at all, I actually enjoy it. Sometimes I just get lost in the nitty gritty of it, especially when trying to teach myself all the stuff.

Okay so for clarification, equity as I understand in laymen's terms is "our share of the pot." So if we have 40% equity then we can use this to determine quickly if a call is +EV, but not anything else correct? So if our call is equal to 40% of the to bet pot, aka call/(current pot+call) = 40% we have a BE move? Just trying to get all these things straight in my head.
