...this, by the way, is mathematical...
Well, there’s a lot of numbers at the top of the page.
And I see pie. It’s blue, so it must be blueberry pie.
EXACTLY! Thank you. As a former math major, I often tell my friends not to fret it if they do not understand this stuff because in order to truly understand it, you have to be able to follow the math. Then and only then can you possibly grasp it. So don’t beat yourself up if you don’t get it. It doesn’t mean you’re dumb.
In my own case, I’m over the hill and far too old to even try to follow the math nowadays. Therefore, I’ll never truly understand it and can only make light of it.
