收集 = mengumpul 比较两个社团收集的瓶子数量：先数位数，位数多的数目比较大。 例子：1 040 和 989 → 1 040 有四位，比较大。 注意：987 的数字 9、8、7 都很大，但它只有三位。

collect = mengumpul Compare the two clubs' totals: count the digits first; the number with more digits is greater. Example: 1 040 and 989 → 1 040 has four digits, so it is greater. Watch out: 987 has big digits 9, 8 and 7, but only three of them.

线索 = petunjuk 按题目的线索把数字放进数位表：千位 9、十位 0、个位 6，剩下的 1 放在还空着的百位。 例子：千位 6、百位 1、个位 3，剩下 9 → 6 193。 注意：每个数字只能用一次，放好以后要再读一次线索检查。

clue = petunjuk Place the digits using the clues: 9 in the thousands, 0 in the tens, 6 in the ones, and the remaining 1 goes in the empty hundreds place. Example: thousands 6, hundreds 1, ones 3, remaining 9 → 6 193. Watch out: each digit is used only once; read the clues again to check.

由小到大 = tertib menaik 先找最小的数（位数最少的），再比较其余两个，从小排到大。 例子：865、1 070、1 007 → 865、1 007、1 070。 注意：978 只有三位数，所以它最小；1 104 和 1 040 要比百位。

smallest to greatest = tertib menaik Find the smallest number first (the one with fewest digits), then compare the others and order from smallest to greatest. Example: 865, 1 070, 1 007 → 865, 1 007, 1 070. Watch out: 978 has only three digits, so it is the smallest; compare the hundreds of 1 104 and 1 040.

按四递增 = menaik empat-empat 从第一张 2 316 开始，每一张加 4：第二、第三……一直到第六张，一共加 5 次。可以画一排格子一个一个写。 例子：从 4 120 按四递增 → 4 124、4 128、4 132。 注意：第六张是加 5 次，不是 6 次。

count up in fours = menaik empat-empat Start with the first chair, 2 316, and add 4 for each chair up to the sixth: five additions altogether. Draw a row of boxes and fill them one by one. Example: counting up in fours from 4 120 → 4 124, 4 128, 4 132. Watch out: the sixth chair needs 5 additions, not 6.

约到千 = ribu terdekat 947 在 0 和 1 000 之间。看百位 9，属于 5–9，所以要进位变成 1 000。 例子：850 约到千 → 1 000。 注意：三位数也可以约到千，答案不会是 900，因为约到千时百位要变成 0。

nearest thousand = ribu terdekat 947 lies between 0 and 1 000. Its hundreds digit is 9, which is in 5–9, so it rounds up to 1 000. Example: 850 rounded to the nearest thousand → 1 000. Watch out: a three-digit number can also be rounded to the nearest thousand; the answer cannot be 900, because the hundreds become 0.

约到哪一位 = bundar kepada tempat apa 分别试约到十、百、千：约到十是 4 480 和 4 520；约到千是 4 000 和 5 000；只有约到百两个都是 4 500。 例子：2 962 和 3 041 约到千都是 3 000。 注意：4 500 的最后两位是 0，但百位不是 0，所以不是约到千。

round to which place = bundar kepada tempat apa Try each place: to the nearest ten they are 4 480 and 4 520; to the nearest thousand they are 4 000 and 5 000; only to the nearest hundred are both 4 500. Example: 2 962 and 3 041 both round to 3 000 at the nearest thousand. Watch out: 4 500 ends in two zeros but its hundreds digit is not 0, so it is not a rounding to the thousand.
