Darab Wang
Langkah 1

Harga sama berulang

Darab digunakan apabila beberapa barang mempunyai harga yang sama.

4 × RM6 = RM24
Harga sama berulang = 相同价钱重复
几样东西价钱都一样时,用乘法比一个个加快:用东西的数量乘相同的价钱。4 × RM6 = RM24 就是4样各 RM6 的东西。例子:买3支笔,每支 RM4,3 × RM4 = RM12。注意:只有每样价钱都一样才能用乘法,价钱不同要用加法。
Harga sama berulang = repeated equal price
When several items cost the same, multiplying is faster than adding them one by one. Multiply the number of items by the price of one: 4 × RM6 = RM24 means four items at RM6 each. Example: three pens at RM4 each cost 3 × RM4 = RM12. Watch out: multiplication only works when every item has the same price; mixed prices need adding.
Langkah 2

Hubung dengan tambah

3 × RM7 sama dengan RM7 + RM7 + RM7.

RM7 + RM7 + RM7 = RM21
Hubung dengan tambah = 和加法连起来
乘法就是重复加同一个数。3 × RM7 就是 RM7 + RM7 + RM7,三个 RM7 加起来是 RM21。一时想不起乘法表,可以用连加来算或检查。例子:4 × RM5 = RM5 + RM5 + RM5 + RM5 = RM20。注意:3 × RM7 是加三次 RM7,不是 RM7 加 3。
Hubung dengan tambah = link to addition
Multiplying means adding the same amount again and again. 3 × RM7 is RM7 + RM7 + RM7, which makes RM21. If you forget a times fact, repeated adding helps you find or check it. Example: 4 × RM5 = RM5 + RM5 + RM5 + RM5 = RM20. Watch out: 3 × RM7 means three lots of RM7, not RM7 plus 3.
Langkah 3

Tulis unit pada jawapan

Tulis hasil darab bersama RM. Dalam bentuk lazim, tulis RM8 di atas dan × 3 di bawah, kemudian darab.

3 × RM8 = RM24
Tulis unit pada jawapan = 答案写单位
钱的乘法答案一定要写 RM。例子:4 × RM8 = RM32,四件 RM8 的东西一共 RM32。也可以用直式:RM8 写在上面,× 4 写在下面。注意:只写 32 没有 RM,别人不知道是钱。
Tulis unit pada jawapan = write the unit
A money product must always show RM. Example: 4 × RM8 = RM32, so four items at RM8 each cost RM32 altogether. You can also use column form: RM8 on top and × 4 below. Watch out: writing only 32 hides that it is money, so always show RM.

3 × RM8 = __

3 × RM8 = 令吉乘法
题目问3个 RM8 一共多少钱。可以背3乘8的乘法表,也可以连加三个 RM8 来检查。答案要写上 RM。例子:3 × RM9 = RM9 + RM9 + RM9 = RM27。注意:别把乘号看成加号,3 加 8 只是 11。
3 × RM8 = multiplying ringgit
The question asks the total cost of three lots of RM8. Use the times fact for 3 and 8, or add RM8 three times to check. Write RM in the answer so it is clearly money. Example: 3 × RM9 = RM9 + RM9 + RM9 = RM27. Watch out: do not read the times sign as a plus sign; 3 plus 8 is only 11.

5 barang berharga RM6 setiap satu. Jumlahnya…

setiap satu = 每一个
题目说5样东西每样 RM6,问总共多少钱。看到 setiap satu 和同样的价钱,就用乘法:数量乘价钱。可用5个 RM6 连加来检查。例子:6本簿子每本 RM4,6 × RM4 = RM24。注意:不要把5和6直接相加,那样只得 RM11。
setiap satu = each
Five items cost RM6 each, and you need the total. The words setiap satu and one repeated price tell you to multiply: number of items times price. Check by adding RM6 five times. Example: six exercise books at RM4 each cost 6 × RM4 = RM24. Watch out: adding 5 and 6 gives only RM11, which is not the total cost.
