Susun Nombor

Tertib menaik bergerak daripada nombor paling kecil kepada paling besar.

Susun Nombor
Langkah 1

Tertib menaik

Tertib menaik bergerak daripada nombor paling kecil kepada paling besar.

205 → 250 → 502
Tertib menaik = 递增顺序
递增就是从最小排到最大。205、250、502 先比百位,502 最大;205 和 250 再比十位,0 比 5 小,所以 205 在前。
例子:413、134、341 递增排成 134 → 341 → 413。
注意:menaik 是越来越大,排完检查每个数都比前一个大。
Tertib menaik = Ascending order
Ascending order goes from the smallest number to the biggest. In 205, 250 and 502, compare hundreds first; then 205 and 250 are compared by their tens, and 0 tens is less than 5 tens.
Example: 413, 134 and 341 in ascending order are 134 → 341 → 413.
Watch out: After sorting, check that each number is bigger than the one before it.
Langkah 2

Tertib menurun

Tertib menurun bergerak daripada nombor paling besar kepada paling kecil.

781 → 718 → 178
Tertib menurun = 递减顺序
递减是从最大排到最小。781 和 718 百位都是 7,比十位 8 比 1 大,所以 781 先;178 百位最小,排最后。
例子:526、652、265 递减排成 652 → 526 → 265。
注意:menurun 是“往下”,第一个要放最大的数,别和 menaik 搞混。
Tertib menurun = Descending order
Descending order goes from the biggest number to the smallest. 781 and 718 both have 7 hundreds, but 8 tens beats 1 ten, so 781 comes first. 178 has the fewest hundreds, so it is last.
Example: 526, 652 and 265 in descending order are 652 → 526 → 265.
Watch out: Menurun means going down, so the biggest number goes first.
Langkah 3

Banding satu demi satu

Cari nombor paling kecil atau paling besar dahulu, kemudian teruskan dengan baki nombor.

kecil ↔ besar
Banding satu demi satu = 一个一个比
数字多时,先找出最小(或最大)的那个,放好后划掉,再从剩下的数里找下一个。这样每次比的数越来越少。
例子:递增排列 390、309、930、93:先放 93,再放 309,然后 390、930。
注意:每放好一个数就划掉,不然同一个数会被用两次或漏掉。
Banding satu demi satu = Compare one by one
With many numbers, first find the smallest or the biggest of them all. Put it in place and cross it out, then search the numbers that are left. Each round you compare fewer numbers.
Example: To put 390, 309, 930 and 93 in ascending order, pick 93, then 309, then 390, then 930.
Watch out: Cross out each number you place, so none is used twice or missed.

Susun secara menaik: 320, 302, 230

Susun secara menaik = 由小到大排
这题要把 320、302、230 由小到大排。先比百位找出最小的数,剩下两个百位相同,就比十位。三个选项的顺序都不同,要逐个检查是否越来越大。
例子:451、415、145 由小到大是 145、415、451。
注意:302 和 320 很像,十位的 0 和 2 决定谁先谁后。
Susun secara menaik = Arrange in ascending order
The question asks you to put 320, 302 and 230 from smallest to biggest. Compare the hundreds to find the smallest, then compare the tens of the two that are left. Check that each choice gets bigger step by step.
Example: 451, 415 and 145 in ascending order are 145, 415, 451.
Watch out: 302 and 320 look alike; their tens digits decide the order.

Susun secara menurun: 614, 641, 416

Susun secara menurun = 由大到小排
这题要把 614、641、416 由大到小排。百位最小的数要放在最后;另外两个百位都是 6,再比十位。检查选项是不是一个比一个小。
例子:857、875、578 由大到小是 875、857、578。
注意:别把“由大到小”看成“由小到大”,方向反了顺序就全倒。
Susun secara menurun = Arrange in descending order
The question asks you to put 614, 641 and 416 from biggest to smallest. The one with the fewest hundreds goes last. The other two share 6 hundreds, so compare their tens.
Example: 857, 875 and 578 in descending order are 875, 857, 578.
Watch out: Do not read menurun as menaik, or the whole order flips.
