It's a great way of explaining a base 20 system, just an odd choice of wording.,(reply>), It actually is still used today (albeit rarely) but now mostly to represent "many" as in "scores of people visit that place each day" rather than the exact number 20.,(reply>), Xavier H. Buying a score of eggs, although, a dozen eggs for 12, a flat of eggs for 36, and a gross of eggs for 144 or 12 dozen are much more common. I can't for the life of me remember what 18 eggs is called. (EDIT: I read that 18 eggs might be called a set by some older folks.) I live in the United States, and we still stubbornly use Imperial measurements too, but we call them SAE, for the Society of Automotive Engineers.,(reply>), when was the last time you heard someone use "score" instead of "20"?,(reply>), I don't know if it was archaic in Lincoln's time but it sure is now. I've never heard it outside of Lincoln's speech and I never knew what it meant before watching this video.,(reply>), That is quite rarely used, and only by older cockneys.<br>It is still archaic.
