Not a one of us had probability in elementary school or learned the fundamental theorem of arithmetic

Have you gone back and checked all your old books? I highly doubt you are remembering correctly what was taught. Old text books are pretty impressive if you actually go back and read one.

I hate to tell you this but when I was in elementary school we did not use text books. The only books we had were those in the library for reading. All problems came either from the chalk board or the mimeograph machine. Did the teacher have a master text probably. I guarantee you that probability was NOT taught in elementary school......We spent our time doing drills for our arithmetic tables. We got fractions in fourth and fifth grade.
