1.So this is going to turn out to be a relatively simple case, because the factorials are going to cancel.
这样将产生一个相对简单的结果，因为阶乘被消去了。
2.If you've got it as a factorial, you've got to expand the factorials.
好吗？如果你得出的结果是一个阶乘，那么你要扩大它的阶乘。
3.This approach is faster than calculating factorials recursively if large factorials are needed many times in the program.
如果程序中多次需要较大的阶乘，此方法则要比递归计算阶乘更快。
4.When will I ever need to do complex factorials or find determinants of multi dimensional matrices?
我将来什么时候会需要做复杂的阶乘或是找出矩阵的行列式？
5.The classic Haskell functions that you'll find in most tutorials are recursive math functions, such as Fibonacci functions and factorials.
在大多数教程中可以发现的大多数经典Haskell函数都是递归的数学函数，例如Fibonacci函数和阶乘。
6.And what's happening is, again, luckily, these factorials are canceling.
就这样，现在发生的是，又是很幸运地，这些阶乘被消掉了。
7.You can think of factorials in much the same way as Fibonacci sequences.
可以用与Fibonacci序列基本相同的方式对待阶乘。
8.In this example, a table of factorials is calculated once.
该示例将计算一次阶乘表。
9.When factorials are needed they are read from the table.
当需要阶乘时，将从该表中读取阶乘。
10.Method of Handling Factorials of Any Size
处理任意大小的阶乘
