Nombor Genap dan Nombor Ganjil

偶数和奇数 = nombor genap dan nombor ganjil 2 的乘法表里的数（2、4、6、8、10……）都是偶数，它们可以平均分成两份。奇数是 1、3、5、7、9……，分成两份时总会多出 1。偶数和奇数在数线上是一个隔一个排列的。 例子：24 在 2 的乘法表里（2 × 12），所以 24 是偶数。 注意：偶数加 1 就变成奇数，奇数加 1 就变成偶数。

even and odd numbers = nombor genap dan nombor ganjil The numbers in the 2 times table (2, 4, 6, 8, 10 and so on) are even; they can be shared equally into two groups. The odd numbers are 1, 3, 5, 7, 9 and so on; when shared into two groups there is always 1 left over. On a number line even and odd numbers take turns. Example: 24 is in the 2 times table (2 × 12), so 24 is even. Watch out: an even number plus 1 is odd, and an odd number plus 1 is even.

除以 2 看余数 = bahagi dengan 2 dan lihat baki 把一个数除以 2：没有余数（余 0），它就是偶数；余 1，它就是奇数。除以 2 的余数只可能是 0 或 1。 例子：45 ÷ 2 = 22 余 1，所以 45 是奇数；60 ÷ 2 = 30，没有余数，所以 60 是偶数。 注意：看的是余数，不是商。商是单数或双数都没有关系。

divide by 2 and look at the remainder = bahagi dengan 2 dan lihat baki Divide the number by 2. If there is no remainder, it is even; if the remainder is 1, it is odd. When dividing by 2 the remainder can only be 0 or 1. Example: 45 ÷ 2 = 22 remainder 1, so 45 is odd; 60 ÷ 2 = 30 with no remainder, so 60 is even. Watch out: look at the remainder, not the quotient; the quotient can be odd or even.

看个位 = lihat digit di tempat sa 一个数是奇是偶，只由个位决定，因为十位、百位、千位、万位的数值都是 10 的倍数，一定是偶数。个位是 0、2、4、6、8 就是偶数；个位是 1、3、5、7、9 就是奇数。 例子：83 146 个位是 6，是偶数；20 007 个位是 7，是奇数。 注意：不要看第一个数字，要看最后一个数字。

look at the ones digit = lihat digit di tempat sa Whether a number is odd or even depends only on its ones digit, because the tens, hundreds, thousands and ten thousands are all multiples of 10, which are even. A ones digit of 0, 2, 4, 6 or 8 means even; 1, 3, 5, 7 or 9 means odd. Example: 83 146 ends in 6, so it is even; 20 007 ends in 7, so it is odd. Watch out: look at the last digit, not the first digit.

分类 = kelaskan 这一题要把方格里所有的偶数都点出来，再按检查。判断方法只有一个：看每个数的个位。个位是 0、2、4、6、8 的是偶数，要点；个位是 1、3、5、7、9 的是奇数，不点。一格一格看，看完全部再按 Semak。 例子：51 390 个位是 0，是偶数；7 423 个位是 3，是奇数。 注意：个位是 0 的数也是偶数，很容易漏掉；不要看最前面的数字来判断。

classify = kelaskan Tap every even number in the grid, then press Semak. There is only one test: look at the ones digit. If it is 0, 2, 4, 6 or 8 the number is even, so tap it; if it is 1, 3, 5, 7 or 9 the number is odd, so leave it. Check every box before pressing Semak. Example: 51 390 ends in 0, so it is even; 7 423 ends in 3, so it is odd. Watch out: numbers ending in 0 are even and are easy to miss; never judge by the first digit.

数偶数 = kira nombor genap 题目给出一串连续的数，从哪里开始、到哪里结束，问里面有几个偶数。做法：先看开头的数是奇数还是偶数，找出最小的偶数；然后每次加 2，一个一个列出来，不超过最后那个数；最后数一数列了几个。 例子：从 521 到 530 的偶数是 522、524、526、528、530，一共 5 个。 注意：开头或结尾是偶数时也要算进去；不要把全部数的个数当成偶数的个数。

count the even numbers = kira nombor genap A list of consecutive numbers starts and ends at the given numbers; how many are even? Check whether the first number is odd or even, find the first even number, then add 2 each time without passing the last number, and count your list. Example: from 521 to 530 the even numbers are 522, 524, 526, 528 and 530, which makes 5. Watch out: an even first or last number counts too, and the total count of numbers is not the count of even ones.

下一个偶数 = nombor genap seterusnya 题目问某个偶数之后的下一个偶数。偶数是两个两个地增加的，所以在原来的偶数上加 2。加的时候要注意进位：个位满十要进到十位，十位满十又要进到百位，一直进下去。 例子：12 598 + 2 = 12 600，个位和十位都进位了。 注意：紧接在后面、只多 1 的数是奇数，不是下一个偶数；进位时前面的数位都可能改变。

the next even number = nombor genap seterusnya What is the next even number? Even numbers go up in twos, so add 2. Watch the regrouping: when the ones make ten, carry to the tens, and if the tens make ten, carry again. Example: 12 598 + 2 = 12 600; both the ones and the tens regroup. Watch out: the number that is just 1 more is odd, and regrouping can change several places at once.
