我是一个统计员,是一个普普通通的青年,只在高中读过一年书。但在党和人民的大力支持下,经过四年多时间的研究,终于创造了快速乘除计算图。这种图的特点是: (1) 速度快:算四,五位除法,可比手摇计算机快一倍以上;比珠算快三,四倍。 (2) 简单易学:十几分钟就可学会。 (3) 比计算尺准确:用大型图能算五位乘除,误差小于万分之一。 (4) 成本低:每套只要几角或一两元。有些图适合于财经部门,还有些小型图适合于工
I am a statistician and an ordinary young person who only read one year in high school. However, with the strong support of the party and the people, after more than four years of research, a rapid multiplication and elimination calculation chart was finally created. The characteristics of this chart are: (1) Speed: Counting four or five divisions can be more than twice as fast as hand-cranked computers; three or four times faster than abacus. (2) Easy to learn: Learn in ten minutes. (3) Accurate than the rule of thumb: With a large graph, it can calculate five multiplications and divisions, and the error is less than one ten-thousandth. (4) Low cost: only a few corners or one or two yuan for each set. Some charts are suitable for the financial sector, and some small drawings are suitable for workers.
