Bina Sifir Darab 1, 0 dan 10

Sebarang nombor darab 1 kekal sebagai nombor itu sendiri.

Langkah 1

Darab 1

Sebarang nombor darab 1 kekal sebagai nombor itu sendiri.

7 × 1 = 7

Darab 1 = 乘以 1
任何数乘以 1，答案都是那个数本身。7 × 1 可以想成 7 组、每组只有 1 个，所以一共 7 个。这条规律对很大的数也一样。
例子：9 × 1 = 9，1 × 25 = 25。
注意：乘以 1 不会让数变大，不要写成多 1 的答案。

Darab 1 = Multiply by 1
Any number multiplied by 1 stays the same. 7 × 1 means seven groups with only one object in each group, so there are 7 objects altogether. This rule works for big numbers too.
Example: 9 × 1 = 9 and 1 × 25 = 25.
Watch out: Multiplying by 1 does not make the number bigger, so do not add one to it.

Langkah 2

Darab 0

Sebarang nombor darab 0 ialah 0 kerana tiada objek dalam setiap kumpulan.

8 × 0 = 0

Darab 0 = 乘以 0
任何数乘以 0，答案都是 0。8 × 0 表示有 8 个盒子，但每个盒子里一个也没有，所以总数是 0。反过来 0 × 8 表示没有盒子，也是 0。
例子：5 × 0 = 0，0 × 12 = 0。
注意：乘以 0 的答案不是原来的数，要和“乘以 1”分清楚。

Darab 0 = Multiply by 0
Any number multiplied by 0 gives 0. 8 × 0 means eight boxes with nothing inside each box, so there is nothing to count at all. Zero boxes, as in 0 × 8, also give 0.
Example: 5 × 0 = 0 and 0 × 12 = 0.
Watch out: Do not mix this up with multiplying by 1; multiplying by zero gives zero, not the number itself.

Langkah 3

Darab 10

Nombor satu digit darab 10 membentuk bilangan puluh yang sepadan.

6 × 10 = 60

Darab 10 = 乘以 10
一位数乘以 10，就得到同样多的“十”。6 × 10 是 6 个十，也就是 60。写法是在 6 后面加一个 0，因为 6 移到了十位。
例子：4 × 10 = 40，即 4 个十。
注意：0 要加在数字后面，6 × 10 写成 06 就错了。

Darab 10 = Multiply by 10
A one-digit number times 10 gives that many tens. 6 × 10 is six tens, which is 60. We write it by putting a zero after the 6, because the 6 moves to the tens place.
Example: 4 × 10 = 40, which is four tens.
Watch out: The zero goes after the digit; writing 06 instead of 60 is wrong.

8 × 1 = __

Darab 1 = 乘以 1 的题目
题目问 8 × 1 是多少。线索是乘数 1：表示 8 组，每组只有 1 个。想一想，每组一个的时候，有几组就有几个。
例子：6 × 1 = 6，因为 6 组各 1 个。
注意：别把乘以 1 和乘以 0 弄混，先看清楚乘的是哪一个数。

Darab 1 = Multiplying by one
The question asks for 8 × 1. The clue is the 1: it means eight groups with just one in each. Think about how many groups there are, because with one in each group, that is the total.
Example: 6 × 1 = 6, since six groups of one make six.
Watch out: Do not mix up multiplying by 1 with multiplying by 0; look carefully at the second number.

7 × 0 = __

Darab 0 = 乘以 0 的题目
题目问 7 × 0。这一题乘的是零，意思是有 7 组，可是每组一个也没有。想象 7 个空篮子放在一起，想一想里面一共能数到几个东西。
例子：4 × 0 = 0，4 个空盒子里什么也没有。
注意：要看清符号是“×”而不是“+”，两种运算的结果不同。

Darab 0 = Multiplying by zero
The question asks for 7 × 0. Multiplying by zero means there are seven groups, but each group is empty. Picture seven empty baskets put together and think about how many things you can count inside them.
Example: 4 × 0 = 0, because four empty boxes hold nothing.
Watch out: Check whether the sign is × or +, because the two operations give different results.
