Given it’s Baltimore, that adds up. Seriously, how proficient in algebra, geometry etc. do you need to be in that environment?
If you can't do A2 + B2 = C2 you are not a functional human being. I tried to teach that to a couple of carpenters! I gave up and I am a pretty good teacher. LOL.
I guess now since the cash registers automatically make change I guess you don’t need algebra.
