数学求助

If at least one factor of a product of integers is even, then the product is even; otherwise the product
is odd. If two integers are both even or both odd, then their sum and their diff erence are even.
Otherwise, their sum and their diff erence are odd. 这两句话请大家给翻一下。
我觉得自己翻译的不对,所以导致这个两句话不对。

如果几个整数的积的因子中至少有一个是偶数,那么这个积就是偶数;否则这个积是奇数。
如果两个整数都是偶数或都是奇数,那么它们的和与它们的差是偶数;否则它们的和与它们的差是偶数。

我觉得不是很难吧。。。。楼主哪里有障碍啊?
