While the math is pretty straightforward, the why would I use this wasn't covered. How often do you use this and for what?

You pretty much never do.
But it is important to know it exists, even if you do not recall the details.
This way when the weird networking thing bites you in the ass, you have the knowledge somewhere in the back of your head that you call pull out of mothballs.

Jared is correct. Basically once you understand how binary makes things work, and knowing how it works in a mask, you never use it. You won't ever need to work in binary, but knowing that it is underneath things helps make something that is super complex, trivially obvious. Basically, if you understand the binary, subnet masking is SO simple. If you don't, it seems like black magic.
