首先我们来看下odd number和even number的大致意思： odd number：词性为noun，odd number是指一个数字不是偶数，即不能被2整除的数。 even number：词性为noun，even number是指一个数字可以被2整除，即能够被2整除的数。

Any integer that cannot be divided exactly by 2 is an odd number. The last digit is 1, 3, 5, 7 or 9. Odd numbers are in between the even numbers. When we add (or subtract) odd or even numbers the results are always: (The same thing happens when we subtract instead of adding.) When we multiply odd or even numbers the results are always:

Odd numbers are the counting numbers whose last digit (or ones place digit) is 1, 3, 5, 7, or 9. In other words, these numbers cannot be equally divided into pairs. It can also be said that the numbers that are not even numbers are odd numbers. For example, 51, 23, 67, 89 are a few numbers that come in the category of odd numbers 1 to 100.

Odd numbers are defined as any number which cannot be divided by two. In other words, numbers in the form of 2k+1, where k ∈ Z (i.e. integers) are called odd numbers. It should be noted that numbers or sets of integers on a number line can either be odd or even. The numbers that are not odd, are even numbers, which are divisible by 2.

2011年8月16日 · 换言之，odd 在英语里的本意是“多余的数字”，而非“奇特的数字”。Odd 的“奇特”实际上衍生自“不见有偶”这个含义。参照 @王宇 的答案，应该可以得出两者没什么关联的结论。

2024年7月14日 · Odd numbers 1 to 100 in maths are numbers that are divided by two resulting in the remainder as one. Suppose we are given a number and its division by two results one as the remainder then it is an odd number. For identifying odd numbers the trick is that the ones digit of the odd number is always 1, 3, 5, 7, and 9.

单数（odd numbers）是数学中正奇数的别称。在数学中与双数（正的偶数）相对，可以表示为形如2n+1的数（n为大于等于0的整数）。

odd翻译：奇怪的, 奇怪的，古怪的；异常的；出人意料的, 不经常, 不常发生的;不经常的, 数字, 奇数的，单数的, 分开的, （指一对或一组事物中）单个的，单只的，不成对的…。

奇数（odd）指不能被2整除的整数 ，数学表达形式为：2k+1， 奇数可以分为正奇数和负奇数。 关于奇数和偶数，有下面的性质： 1、两个连续整数中必有一个奇数和一个偶数。

2024年12月6日 · 键盘输入一个正整数n，编程判断该数是奇数还是偶数，如是奇数则输出信息“odd”，如是偶数则输出“even”。 输出 ：如是 奇数 则 输出 信息“ odd ”，如是偶是则 输出 “ eve n”。
