据说父亲的父亲就是一个数学天才,他可以通过心算完成一大堆数字的加法。
It was said that his own father was a numerical genius who could add up large columns of Numbers in his head.
在这些心算步骤中,每个时刻只有一些数字被特殊地选择用于加法运算的被加数,而其他的数字则仅仅保存在工作记忆中并不用于当前操作。
During these steps, some digits are selected for specific roles (e. g., first addend) in the addition operation, while the others are held in working memory, but not used in the current operation.
我不能心算一长串数字的加法,那是计算器做的事情。
That's what jacks are for. I can't add long columns of figures in my head.
学习珠心算就像去健身房,使得你儿童的大脑变得更灵活,和对加法,减法,乘法和除法的运萛更强。
Learning the abacus is like going to the gym to exercise your brain as it becomes faster and stronger through mental calculations for addition, subtraction, multiplication and division.
