Reply To: 2nd grade math Egyptian numerals
APH has available an addendum to the Nemeth Code called "Ancient Numeration Systems", adopted by BANA 1988. Rule V deals with Egyptian Signs and Symbols. I don't know what your Egyptian numerals look like, but this might be the answer for you. Rule I of the Addendum explains the use and format of the symbols from Attic, Babylonian, Chinese-Japanese, Egyptian, Greek, Hebrew, and Mayan.
