How many thousands make a million?

To understand how many thousands make a million, we need to first understand the concept of place value and how numbers are written.

Place Value:
In the decimal system, numbers are written using place value. Each place value represents a power of 10. For example:
- The ones place represents 10^0.
- The tens place represents 10^1.
- The hundreds place represents 10^2.
- The thousands place represents 10^3.
- And so on...

Understanding Thousands and Millions:
- The term "thousand" represents the value 1000, which means 1000 ones.
- The term "million" represents the value 1,000,000, which means 1,000 thousands or 1,000,000 ones.

So, to find out how many thousands make a million, we need to divide a million by a thousand.

Calculating Thousands in a Million:
1,000,000 ÷ 1,000 = 1,000

Therefore, there are 1,000 thousands in a million.

The correct answer is option 'C' - 1000. When we divide a million by a thousand, we get 1000, which means that there are 1000 thousands in a million.

Summary:
- In the decimal system, numbers are written using place value.
- The term "thousand" represents the value 1000, and "million" represents the value 1,000,000.
- To find out how many thousands make a million, we divide a million by a thousand, resulting in 1000.

Key Points:
