Numbers are divided into two different things. 数字分为两组不同的数。

　　There are odd numbers and even numbers. 它们是奇数和偶数。

　　An even number ends with zero, two, four, six or eight. 偶数以数字0，2，4，6或8结尾。

　　It is divisible by two without a remainder. 它们由2整除没有余数。

　　On the other hand, an odd number ends with one, three, five, seven or nine. 另一方面，奇数以数字1，3，5，7或9结尾。

　　An odd number is not divisible by two at all. 奇数根本就不能被2整除。

　　Do you know that zero is also an even number? 你知道零也是偶数吗？
