相反数是一个数学术语,指绝对值相等,正负号相反的两个数互为相反数。相反数的性质是他们的绝对值相同。例如:-2与+2互为相反数。用字母表示a与-a是相反数,0的相反数是0。这里a便是任意一个数,可以是正数、负数,也可以是0。
...线上从原点向右(或上)为正方向,从原点向左(或下)为负方向; (3)选取适当的长度为单位长度。 6.相反数(opposite number):绝对值相等,只有符号不同的两个数叫做互为相反数。

在直线上任取一个点表示数0,这个点叫做原点(origin)。 只有符号不同的两个数叫做互为相反数(opposite **mber)。(例:2的相反数是-2;0的相反数是0) 数轴上表示数a的点与原点的距离叫做数a的绝对值(absolute value),记作|a|。

我们可以先用一下,然后加个负号,但是我要说明,ndS正好是这个的相反数。
Well, we could use it and then subtract, but I was just going to say that ndS is actually the opposite of this.
