一、达到了怎样程度? 小学学完算术和珠算。算术包括整数、分数、小数,还有百分法、比例,以及常用的计量单位,简单几何形体的初步知识,简单的统计图表。比现行课本,增加了用辗转相除法求最大公约数、循环小数化分数、棱柱棱锥的体积计算、较复杂的应用题等内容。珠算包括整数、小数的四则计算和记账的初步知识各个部分的要求,特别是计算能力和解答应用题能力方面的要求,比现行课本,有所提高。 First, to what extent? Elementary school arithmetic and abacus. Arithmeticals include integers, fractions, decimals, as well as percentages, proportions, and commonly used units of measurement, initial knowledge of simple geometries, simple statistics charts. Compared with the current textbook, the addition of the most common divisor by the method of dividing and dividing by rotation, the calculation of the volume of prismatic pyramids, and the application of more complicated questions are added. Beads count, including integer, fractional four calculations and accounting of the initial knowledge of the various parts of the requirements, especially the ability to calculate and answer questions ability, than the current textbook has improved.
