summation

音标发音

This expression is used inside the braces {} that define the index of the summation. The syntax for an expression is
这个表达式在花括号（{}）中使用，它定义了和的索引。
If you get imbalance in AJT 40 or 60, check that there is no data on any summation account (that has formerly been an in data account).
如果 AJT 40 或 60 中出现不平衡，检查确保在任何合计账户（以前一直是一个数据账户）上没有数据。
In reality, we would probably express this more compactly using a method reference to the size() method for our mapper and a predefined reducer for integer summation
在现实情况中，我们的表达方式可能会更紧凑一些，我们的mapper会使用一个size()方法的方法引用，以及整数的求和会用到一个预先定义的reducer

with someone else who's standing next to you, you're going to sum your numbers together and one of you whoever is fastest probably is going to sit down and the other person is going to take on his or her number, the summation of those numbers; and then you're going to repeat and if you follow the logic here in just a few moments, there should be just one of you very awkwardly standing.
你们需要与站在你下面一个的你结成一对,把你们的数字相加,你们中最快的那个可以坐下,其他人将接着他的那个号码继续进行，计算这些数字的和，以此重复,如果你们遵循了这一逻辑，最后将只有一个人呆呆地站着。

If you have a sample with n observations, it's the summation I = 1 to n of xi/n--that's the average.
如果你有n个观测值,对Xi从i=1到n求和再除以n
