找奇数 = cari nombor ganjil 三个数用的数字差不多，要找出哪一个是奇数。只看每个数的个位：个位是 1、3、5、7、9 的就是奇数。数里其他位置有没有单数都没有关系。 例子：31 865 个位是 5，是奇数；58 136 个位是 6，是偶数。 注意：数字相同、排法不同的数，个位不一样，奇偶也就不一样。

find the odd number = cari nombor ganjil The three numbers use similar digits; which one is odd? Look only at the ones digit: 1, 3, 5, 7 or 9 means odd. Odd digits in other places do not matter. Example: 31 865 ends in 5, so it is odd; 58 136 ends in 6, so it is even. Watch out: the same digits in a different order can give a different ones digit, so odd or even can change.

在两数之间 = di antara dua nombor 题目问“在两个数之间”的偶数。“di antara”表示不包括两端的数，只算中间的。做法：从比前面那个数大的最小偶数开始，每次加 2，写到比后面那个数小为止；再检查每个数的个位都是双数。 例子：在 540 和 548 之间的偶数是 542、544、546；540 和 548 是两端，不算。 注意：两端的数就算是偶数也不算进去；奇数的一组一定不对。

between two numbers = di antara dua nombor Which even numbers lie between the two numbers? Di antara means the two end numbers are not included. Start at the smallest even number after the first number, add 2 each time and stop before the second number. Check that every ones digit is even. Example: the even numbers between 540 and 548 are 542, 544 and 546; the ends 540 and 548 do not count. Watch out: an end number does not count even if it is even.

余数说明什么 = maksud baki 一个数除以 2，如果有余数 1，就表示它不能平均分成两份，这个数是奇数；如果没有余数，就是偶数。要判断的是“被除的数”，不是除出来的商。 例子：39 ÷ 2 = 19 余 1，表示 39 是奇数；46 ÷ 2 = 23，没有余数，表示 46 是偶数。 注意：商也可能是奇数或偶数，但题目问的是被除数的性质，不要把商和被除数弄混。

what the remainder tells us = maksud baki If a number divided by 2 leaves a remainder of 1, it cannot be shared into two equal groups, so it is odd; with no remainder it is even. We judge the number being divided, not the quotient. Example: 39 ÷ 2 = 19 remainder 1, so 39 is odd; 46 ÷ 2 = 23 exactly, so 46 is even. Watch out: the quotient can be odd or even too, but the question is about the number being divided.

数偶数 = kira nombor genap 题目问一个范围里有几个偶数。先看两端是奇数还是偶数；再从范围里最小的偶数开始，每次加 2 列出来，不超过终点；最后数一数列出的个数。 例子：从 91 到 99 的偶数有 92、94、96、98，共 4 个。 注意：范围里全部数的个数不等于偶数的个数；两端是奇数时不要算进去。

count the even numbers = kira nombor genap How many even numbers are in the range? Check whether the ends are odd or even, start from the first even number, add 2 each time without passing the end, and count your list. Example: from 91 to 99 the even numbers are 92, 94, 96 and 98, which makes 4. Watch out: the number of all the numbers in the range is not the number of even ones, and odd ends are not counted.

前一个奇数 = nombor ganjil sebelumnya 题目问在某个数之前、最接近它的奇数。“之前”就是往小的方向数。先判断这个数本身是奇数还是偶数：如果是偶数，紧挨在它前面的那个数（少 1）就是奇数。少 1 的时候要注意借位。 例子：40 000 前一个奇数是 39 999，因为 40 000 是偶数，减 1 时要一路借位。 注意：比它大的数在它后面，不算“之前”；少 2 的数个位和它一样是双数。

the odd number before = nombor ganjil sebelumnya Find the closest odd number before the given number. Before means counting down. If the number is even, the number just below it (1 less) is odd. Watch the regrouping when you take away 1. Example: the odd number before 40 000 is 39 999; taking 1 from 40 000 needs regrouping all the way. Watch out: bigger numbers come after, not before, and a number 2 less is still even.

只看个位 = lihat tempat sa sahaja 题目要你判断一个同学的说法对不对。判断一个数是奇数还是偶数，方法只有一个：看它的个位。先找出这个数的个位数字，决定它是奇数还是偶数，再和同学的说法比较。 例子：70 000 的个位是 0，所以 70 000 是偶数；30 001 的个位是 1，它是奇数。 注意：判断奇偶时只看个位这一位。

look only at the ones = lihat tempat sa sahaja Decide whether the pupil is right. There is only one way to tell odd from even: look at the ones digit. Find it, decide odd or even, then compare with what the pupil said. Example: 70 000 ends in 0, so it is even; 30 001 ends in 1, so it is odd. Watch out: use only the ones digit to decide odd or even.
