Sixth, the mathematical nature of the volume This article deals with the division of primary school arithmetic calculation, fractional calculation, ratio or ratio calculation; the number of objects (natural number, fraction), the amount of points; the amount of another similar amount, non-similar amount of points. Through discussion, we know that it is easy to discuss division, score, ratio or ratio by just numbers.
