Kenal pasti kumpulan = 认出组的资料
乘除应用题里通常有三种数：组数、每组的数量和总数。先看题目已经给了哪两种，要你找的是哪一种。知道缺哪一个，才能选对算法。
例子：“4 个书架，每个放 9 本书”，要找总数：4 × 9 = 36 本。
注意：“每”字后面的数通常是每组的数量，不是组数。

Kenal pasti kumpulan = Identify the groups
Multiplication and division problems usually have three kinds of numbers: the number of groups, the amount in each group, and the total. First see which two are given and which one is missing. The missing one decides the operation.
Example: '4 shelves with 9 books on each' asks for the total: 4 × 9 = 36 books.
Watch out: The number after 'each' is usually the amount per group.

Darab atau bahagi = 乘还是除
要找总数，就用乘法：组数 × 每组数量。已知总数，要找组数或每组几个，就用除法：总数 ÷ 已知的那个数。选对运算后再计算，会少很多错误。
例子：32 个学生每 8 人一队，有几队？已知总数找组数，用除法：32 ÷ 8 = 4 队。
注意：总数已经给了还用乘法，答案会大得不合理。

Darab atau bahagi = Multiply or divide
To find a total, multiply: groups × amount in each group. When the total is known and you need the number of groups or the amount in each, divide: total ÷ the number you know. Choose first, then count.
Example: 32 pupils form teams of 8. How many teams? The total is known, so divide: 32 ÷ 8 = 4 teams.
Watch out: Multiplying when the total is already given makes the answer far too big.

Tafsir baki = 解读余数
有余数时，要按故事决定怎么回答。有时余下的可以不管，例如问“能装满几盒”。有时要多加一组，例如问“至少要几辆车”，因为剩下的人也要坐车。
例子：26 人坐车，每车 5 人：26 ÷ 5 = 5 余 1，剩 1 人也要坐，所以要 6 辆车。
注意：问“至少要几个”时，常常要为余数再加一组。

Tafsir baki = Interpret the remainder
When there is a remainder, the story decides the answer. Sometimes the leftover is ignored, such as 'how many boxes can be filled'. Sometimes one more group is needed, such as 'how many cars are needed', because leftover people need a ride too.
Example: 26 people ride in cars of 5: 26 ÷ 5 = 5 remainder 1, so 6 cars are needed.
Watch out: Asking for the least number needed often means one extra group.
