While in Israel this summer I copied the license plate number of a car that had sideswiped our bus. In the ensuing conversation with the driver I mentioned something about Arabic as opposed to Roman numerals. He was perturbed, insisting that the conventional numerals were NOT Arabic! When we stopped in Jericho he asked an Arab sales clerk to write the traditional arabic numbers for me. They were similar to, but not identical with the the conventional American numerals that we call "Arabic." I've been searching the WEB for the reasoning behind our acceptance of the numerals as Arabic, to no avail. One discussion, from several years ago, suggests that the system was Akkadian and/or derived from the Sumerian. So why do we call it Arabic? If anyone can give me a simple explanation, I'd appreciate hearing from you. Sincerely, Sally B, a retired 2nd grade teacher.
