是多少呢？是的。，What，is，z？，Yup，，so，it’s，plus，2。,它是+2所以电荷量实际上仅仅等于，我们可以写+2或者你可以写，仅仅指一个电子电荷量，e，just，means，the，absolute，value，of，t,的绝对值。
z z So the charge is actually just equal to z, +2e we can write plus 2, or you can write plus 2 e, e he charge on an electron.
在这种情况下你最好的选择是使用绝对值做模运算符时如果你想基本整数的除法。
Your best bet in situations like this is to operate on absolute values when doing modulo operators if you want basic integer division.
当你站在它的位置，让您的绝对值和腰部紧来支持你的脊椎。
When you do it in a standing position, keep your abs and lower back tight to support your spine.
这些东西并不是试图给出获得认证价值的绝对值，而是你可以拿它作出比较，可以帮助你选择你的学习路径。
These mechanisms don't attempt to give some sort of absolute value of a certification, but rather one objective comparison that might help you choose.
