Why is (n-1)(n+1)=n^2-1?

And you are left with almost a square. One less than the square of side n.

The more direct answer is to look at a rectangle with sides of n + 1 and n - 1, let’s go with n = 2

So, that’s a rectangle with sides 2 and 4.

Why is it after eating almonds when I’m occupied, I don’t feel mild itch, but as soon as I have nothing to do, I feel mildly itchy?

(n - 1)(n + 1)

Move the nub up to the top:

n^2 - 1

The basic answer is that you cross-multiply the values in each factor:

Why is the mainstream media, traditionally liberal except for Fox, not reporting on Trump like he's a traditional candidate who has ideas, values, and a concern for the common good?

If you cut off the end of that rectangle, you make it smaller, 2 * 3 and a separate nub of size 1 * 2
