比较 = banding 两个五位数要比大小，先对齐数位，从万位开始比。相同就往右移，遇到最先出现不同的数位，数字大的那个数就比较大。 例子：15 800 和 15 080 → 万位、千位相同，百位 8 比 0 大，所以 15 800 较大。 注意：两个数有相同的数字时，只看数字的样子会看错，要看每个数字在哪一位。

compare = banding To compare two five-digit numbers, line up the places and start from the ten thousands. Move right while the digits are the same; the first different place decides which is bigger. Example: 15 800 and 15 080 match in the first two places, and in the hundreds 8 is bigger than 0, so 15 800 is bigger. Watch out: when both numbers use the same digits, look at the place of each digit, not just the digits.

找最小 = cari paling kecil 要从三个数里找最小的。三个都是五位数，就先比万位：万位数字最小的那个数最小，后面的数位不用再看。万位相同才需要比千位。 例子：19 999 和 20 000 → 万位 1 比 2 小，所以 19 999 较小。 注意：后面有很多 9 的数，看起来很大，其实大小由最高位决定。

find the smallest = cari paling kecil Find the smallest of three five-digit numbers. Compare the ten thousands first; the number with the smallest digit there is the smallest, and the later places do not matter. Only if those digits match do you compare the thousands. Example: 19 999 and 20 000: 1 is smaller than 2, so 19 999 is smaller. Watch out: a number with many 9s at the end looks big, but the highest place decides.

降序 = tertib menurun 要找出从大到小排好的一组。先找出最大的数：位数多、万位大的数较大；前面几位都相同的，就往右比到不同的那一位。然后拿每个选项，检查每一个数是不是都比后面的数大。 例子：降序 81 700、81 070、18 700。 注意：只要有一对相邻的数次序不对，整组就不是降序；四位数一定排在五位数后面。

descending = tertib menurun Find the list that goes from largest to smallest. Compare the numbers place by place from the left. Then check each option: every number must be bigger than the one after it. Example: descending 81 700, 81 070, 18 700. Watch out: if even one neighbouring pair is in the wrong order the list is not descending, and a four-digit number always comes after the five-digit ones.

符号 < 的意思 = maksud simbol < 题目用两个“<”把 M 夹在中间：左边的式子表示 M 比左边那个数大，右边的式子表示 M 比右边那个数小。所以 M 要在两个数之间。逐个选项检查这两个条件。 例子：20 100 < M < 20 300，M 可以是 20 250，因为它比 20 100 大、比 20 300 小。 注意：“<”尖的一边指向较小的数；只符合一个条件的数不行。

the sign < = simbol < The two < signs trap M in the middle: the left part says M is bigger than the first number and the right part says M is smaller than the second. So M lies between them. Test each option against both conditions. Example: if 20 100 < M < 20 300, M could be 20 250. Watch out: the pointed end of < points to the smaller number, and meeting only one condition is not enough.

数线的右端 = hujung kanan garis nombor 数线从左到右越来越大，右端是最大的数。题目问哪个数最靠近右端，也就是问三个数里哪一个最大。按数位从左往右比较，找出最大的数。 例子：在 30 000 到 31 000 的数线上，30 990 比 30 099 更靠近右端。 注意：数字相同但位置不同的数，大小差很多；百位的数字比十位的更重要。

right end of a number line = hujung kanan garis nombor Numbers grow from left to right, so the right end is the biggest. The number closest to the right end is the largest of the three. Compare them place by place from the left. Example: on a line from 30 000 to 31 000, 30 990 is closer to the right end than 30 099. Watch out: the same digits in different places give very different sizes; a hundreds digit matters more than a tens digit.

判断谁对 = siapa yang betul 两个人对同一对数的大小说法相反，要判断谁对。自己先比较：对齐数位，从万位开始比，最先出现不同的数位决定大小。再看谁的说法和你比较的结果一样。 例子：70 002 和 69 998 → 万位 7 比 6 大，所以 70 002 较大。 注意：一个数里 9 多，不代表它比较大；两个说法不可能同时都对。

who is correct = siapa yang betul Two pupils say opposite things about the same pair of numbers. Compare them yourself: line up the places and start from the ten thousands; the first different place decides. Then see whose statement matches. Example: 70 002 and 69 998: 7 is bigger than 6, so 70 002 is bigger. Watch out: having many 9s does not make a number bigger, and two opposite statements cannot both be right.

降序中插入新数 = masukkan nombor dalam tertib menurun 这四个数是按降序（从大到小）排的，现在放进一个新数，问哪一个在正中间。先把新数和每个数逐位比较，找到它在降序里的位置；五个数重新排好以后，排第三位的数就在中间。 例子：62 500、61 800、60 900、6 800 加入 61 200 → 62 500、61 800、61 200、60 900、6 800，中间是 61 200。 注意：列表是降序，新数要按从大到小的方向放；数字很像的数要比到不同的那一位。

insert into a descending list = masukkan nombor dalam tertib menurun The four numbers go from largest to smallest, and a new number joins them. Compare the new number digit by digit to find its place in the descending list, then take the third of the five numbers. Example: 62 500, 61 800, 60 900, 6 800 plus 61 200 gives 62 500, 61 800, 61 200, 60 900, 6 800, so the middle is 61 200. Watch out: keep the descending direction, and compare similar-looking numbers until a place differs.
