COUNTING, READING AND WRITING IN MILLIONS
When it comes to numbers and numeration, nothing is more important than the ability to count and read and write in millions. This skill allows you to effectively communicate with large groups of people and work with large amounts of data or information.
There are many different strategies that you can use to improve your ability to count, read, and write in millions. One effective strategy is to break down the numbers into smaller, more manageable chunks that are easier to process. You can also use different mnemonic devices or visual aids to help you remember the order of numbers and their corresponding values.
Whenever you want to break down, you will need to break them down in groups of three that are separated by comma.
Example 1: Write 11001121 in words
Solution: You will need to break down the digit into the group of three by using comma
The answer will be like this
11,001,121= Eleven million, one thousand, one hundred and twenty-one.
Example 2: Write 239543023 in words
Solution: You will need to break down the digit into groups of three by using comma
The answer will be like this
23,954,302,3= Twenty-three million, nine hundred and fifty-four thousand, three hundred and two point three.
With practice and dedication, you can improve your skills in counting, reading, and writing in millions and start communicating very well by writing out big numbers in words.

Find place value and value of any digit in any given whole number
Place value is the position of the given figure in the numeric table. Finding the value of any digit in a whole number can be done by locating it in its corresponding place value, which will give you the full value of the digit.
The numeric table is divided into columns with sub-columns that are also divided into Hundreds, Tens and Units.
The major headings of the numeric table are ones, thousands, millions, billion etc.
For example, to find the place value and value of any digit in 4758293435, we would first look at how each individual digit is organized in the number.
We can expand the number in the following way
4758293435=4000000000+700000000+50000000+8000000+200000+90000+3000+400+30+5
Expansion of numbers makes it very easy to calculate the place value of anu given figure
More examples
- What is the place value of 6 in 45360 Solution: 40000+5000+300+60+0. The place value of 6 in 45360 is 60 or 6 tens.
- What is the place vale of 1 in 1003 Solution: 1000+000+00+0 . The place value of 1 in 1003 is 1000 0r 1 thousand
