multiplicative identity

基本解释

The multiplicative identity is 1, that is, multiplying any number by 1 will yield that same number.
乘法的交换和关联；进一步它分配了加减。倍增的身份是1 ，也就是说，任何数字乘以1将产生同样的号码。

The number 1 in its multiplicative identity is practically bedridden, leaving other numbers unchanged: 6 times 1 equals 6.
数字“1”在乘法中起一种限制作用，就是让其他数字保持不变：6乘以1还等于6。
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.
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。
