1. In English we call it an abacus.
在英语里我们叫它为一个算盘。
- abacus (n.) late 14c., "sand table for drawing, calculating, etc.," also "art of calculating with an abacus," from Latin abacus, from Greek abax (genitive abakos) "counting table, board for drawing," of uncertain etymology. It is said to be from a Semitic source, Phoenician or Hebrew abaq "sand strewn on a surface for writing," literally "dust," from the Semitic root a-b-q "to fly off," but Beekes and others find this "semantically weak."
