一数(讀作Shù)起源于数(讀作Shǔ),如一二三四五……,一个两个三个……地数。量(讀作Liàng)起源于量(讀作Liáng),先取一个单位做标准,然后一个单位一个单位地量。天下虽有各种不同的量,各种不同的量这些量的单位,如尺、斤、斗、秒、伏特、欧格和卡路里等等,但都必須通过数才能确切地把实际的情况表达出來。所以“数”是各种各样不同量的共性,必須通过它才能比較量的多寡,才能說明量的变化。“量”是貫穿到一切科学領域之内的,因此,数学的用处也就渗透到一切科学領城之中。凡是要研究量,量的关系,量的变化,量的关系的变化,量的变化的关系的时候,就少不了数学。不仅如此,量的变化还有变化,而刻划变化一般也是尽量来刻划的,例如,速度是用来描写物体的变化的动态的,而加速度則用来刻划速度的变化。量与量之間有各种各样不同的关系, One number (pronounced Shù) originates from the number (read as Shǔ), such as one two three forty-five,..., one, two, three,... Land. The quantity (read as Liàng) originates from the quantity (read as Liáng), and takes one unit as the standard, then one unit and one unit. Although there are all kinds of different quantities in the world, various quantities of these quantities of units, such as feet, jins, buckets, seconds, volts, oggs, and calories, etc., all must pass the numbers in order to accurately express the actual situation. come out. Therefore, “number” is the commonality of all kinds of different quantities, and it must be through it to compare the amount of quantity in order to explain the change in quantity. “Quantity” is permeated in all fields of science. Therefore, the usefulness of mathematics is also infiltrated into all scientific centers. Whenever the relationship between quantity, quantity, quantity, quantity, and quantity is studied, mathematics is indispensable. Not only that, there are changes in the amount of change, and the characterization changes are generally characterized as much as possible, for example, the speed is used to describe the dynamics of the change of the object, and the acceleration is used to characterize the change in speed. There are a variety of different relationships between quantity and quantity.
