what is the expanded form of a number?what down an example.答案用英语写一段完整的话,带翻译

Expanded Form is a way to break up a number to show how much each digit in the number represents.In other words,expanded form is the method of pulling a number apart and expressing it as a sum of the values of each digit.
展开形式,是一种通过分离一个数（一般是有几个数位的数）,来展示每个在这个数里的数字（是单独的数位上的数字）表示多少的方法.用其他的话来讲,展开形式是一种方式,把数给分开,并且将它作为一个各数字（是单独的数位上的数字）值的和来表达它.
The best way to identify the expanded form of a number is to simply write the number in words.
最好的识别“一个数字的展开形式”的方法,是简单的将数字以文字形式书写.
In order to understand expanded form better,one needs to be good at place value.
Consider the number 543.
为了更好地理解展开形式,需要对位值擅长.
比如说数字543
the value of 5 is 5 × 100=500
the value of 4 is 4 × 10=40
the value of 3 is 3 × 1=3
5在这个数字中的值是5 × 100=500（5在百位,代表500）
4在这个数字中的值是4 × 10=40（4在十位,代表40）
3在这个数字中的值是3 × 1=3（3在个位,代表3）
Therefore,the expanded form of the number 543 is 500 + 40 + 3.
所以,543的展开形式是500 + 40 + 3.
注：英语部分绝对没有错误,是百科里面的内容,然后中文是我的翻译,有些翻的很不好,但在括号里有补充.如果有不懂继续问我.
