How important is Math and SHHE?

[maka2184]

Just to make sure this isn't just a retarded question asking how important it is to calculate pot odds etc. As you play higher stakes, metagame consideration and the players become much more important to the point where hands are played much more differently.

Now, how important does understanding Math become as you play in these stakes? What I mean is when you're playing do you calculate pot equity, fold equity, whether the play is mathematically +EV based on HUD statistics and recent/past history?

Maybe this is a foolish question that doesn't belong in this forum but I realized I rarely try to get the exact mathematical numbers when I'm playing. Based on tracker and HUD statistics you can make general assumption on certain mathematical considerations, but I never do the entire calculations in my head to figure things out. I'm sure very few are mathematical geniuses where they can multi table and figure out exact numbers in their head, or do you become that good as you become accustomed to high level play? Or do you make generalizations as well, and if so what kind of mathematical aspects of poker do you take into consideration as you play each hand?
