NUMERICAL PLACE VALUE SYSTEMS
by: Staff

The question:


1.what are the different periods?
2.how are the different periods separated from one another?

The answer:



Since you didn’t specify what kind the periods you are asking about, I am going to assume your question is a general question about NUMERICAL PLACE VALUE SYSTEMS.

(You could be asking about a totally different subject, such as periodic functions, or repeating decimals. I just can’t tell from your question.)

In the Philippines where you live, I assume you are using the INTERNATIONAL PLACE VALUE System (Base 10 Numbering system).

Using the International Place Value System, the number three million, four hundred and sixty nine thousand, and thirty three would be written as:

3,469,033

Notice that the position of each digit determines its value. That is how a place value system works.

The face value of a digit is not the same as its place value.

For example, reading from left to right, the 3 on the far left represents three million because of its position with respect to the other digits (it is the seventh digit from the right). Its face value is just 3. Its PLACE determines its real value of three million. The same digit (of 3) on the far right only represents a value of 3.

That said - this is the answer to your first question: what are the different periods?

Each group of 3 digits is a period. Each group of 3 digits has a different name.

Here is an example of a very large number: 123,456,789,987,654

The names of the periods are:

123 – Trillion
456 – Billion
789 – Million
987 – Thousand
654 – Ones



This is the answer to your second question: how are the different periods separated from one another?

In the United States the separator which divides one period from the other is the COMMA.

However, other countries often use different separators in place of the comma. Examples of other separators may include: a space between periods, a decimal point between periods, a dash between periods, a ^ between periods, an apostrophe between periods, etc.





Thanks for writing.
