I'm in my late 30s, I recently started learning math again. I'm going back to the point I dropped out myself. highschool level.

somehow I managed to get a CS degree but I don't really understand how to simplify an algebra equation lol

and don't even get me started on geometry! I don't know who Sine, Cosine and Tangent are, but they haunt my dreams! they're always standing in a circle, it's freaky.
