I'm enjoying it a lot and don't consider myself to be very good at math nor do I pay much attention to the specific calculations. I also feel they might as well have printed some of that stuff in a different language as far as I'm concerned. But there's more than enough simple meat in there to still make it worthwhile and they mostly just throw in the equattions and calculations for those who care and for completeness.
You don't even need to bother trying to figure out the calculations since the text usually gets the general point across anyway.
