算盤(abacus)是中國傳統(tǒng)的計(jì)算工具,也是中國古代的一項(xiàng)重大發(fā)明。阿拉伯?dāng)?shù)字出現(xiàn)以前,算盤在世界各地廣泛使用。算盤是矩形的木框,木框上固定著帶算珠的木桿。木框中間的橫梁(beam)將木桿分成兩部分:木桿上方的兩顆算珠 (counting beads)每個(gè)代表5,下方的五顆算珠每個(gè)代表1。隨著算盤的應(yīng)用,人們總結(jié)出很多計(jì)算技巧,提高了計(jì)算速度。由于算盤易于制造,而且計(jì)算口訣易于記憶和操作,因此算盤在中國十分流行。
As a traditional Chinese calculation tool and an important ancient Chinese invention,the abacus was widely used before the invention of Arabic numerals in the world. The abacus is a rectangle with a wooden frame. Within the frame,rods with stringed beads are fixed. The beam in the middle of the frame divides each rod into two parts.
The two counting beads in the upper part of each rod represent five and the rest five beads in the lower part represent one. With the application of the abacus, people summarized many calculation tips to help improve the speed of calculation. As the abacus is simple to produce, and its calculation tips are easy to memorize and operate, it is quite popular in China.
詞句點(diǎn)撥4.隨著算盤的應(yīng)用:可譯為 with the application of the abacus。
