Look at this table which shows the place value of numbers up to millions.
You should know the value of each column and understand how each number is written.
In 6,025 the 6 is in the thousands column, so is worth 6,000.
In 6,092,047 the 6 is in the millions column, so is worth a massive 6,000,000.
In 1,234,567 the 6 is only in the tens column, so is worth only 60.
Note the use of a comma to separate every third digit from thousands onwards. This is the usual way to show large numbers and make it easier to read them, although sometimes you will see large numbers with spaces used instead of commas.
