矢量乘法有两种,一种叫做“点积“,通常也被叫作“数量积
There are two ways that we multiply vectors and one is called the "dot product" often also called the scalar product.
利用矩阵的最重要的好处是任何数量的颜色转换，可以使用标准的组成矩阵乘法。
The most important advantage of using matrices is that any number of color transformations can be composed using standard matrix multiplication.
种族进化史研究表明，动物具备算术能力，它们运用数量感来表征可数与不可数的数量，并以此为基础进行加法、减法、乘法和除法运算。
It means they can represent countable and uncountable quantity with mental magnitude. They can perform addition, subtraction, multiplication and division.
此外，乘法逆是互惠的任何数量，也就是乘以倒数任何数目的数量本身将产生倍增的身份。
Also, the multiplicative inverse is the reciprocal of any number, that is, multiplying the reciprocal of any number by the number itself will yield the multiplicative identity.
